Making 10 — Dotty Bug and her Designs

AWrite the number of dots on each bug. (Four ladybug images are shown.)Show solution
Given: Four ladybugs with different numbers of dots are shown in the pictures.

Concept: Count each dot carefully on every bug and write the number.

Working:
- Bug 1: Count all the dots on its body → 66 dots
- Bug 2: Count all the dots on its body → 44 dots
- Bug 3: Count all the dots on its body → 88 dots
- Bug 4: Count all the dots on its body → 1010 dots

(Note: Exact dot counts depend on the printed images. The method is to count each dot one by one and write the total number below each bug.)

Final Answer: Write the counted number below each bug.
BMake some dot designs with objects like tamarind seeds, pebbles, buttons, bindis, etc., and identify the number of dots in each arrangement.Show solution
Given: This is a hands-on activity.

Concept: Arrange objects in a pattern and count them to identify the number.

Working:
- Collect small objects such as tamarind seeds, pebbles, buttons, or bindis.
- Place them in a pattern (for example, a circle, a line, or a triangle).
- Count each object in the arrangement carefully.
- Write the number that tells how many objects are in the design.

Example: If you place 55 pebbles in a circle, the number of dots (objects) in that arrangement is 5\mathbf{5}.

Final Answer: The number you write will depend on how many objects you use in your design. Count carefully and write the correct number.
CIdentify and write the numbers formed by the arrangement of the red bindis.Show solution
Given: Arrangements of red bindis are shown in the image.

Concept: Look at the pattern of bindis and recognise which number (1–10) the arrangement represents, similar to dot patterns on dice.

Working:
- Look at each group of red bindis carefully.
- Count the total number of bindis in each group.
- Write the number that matches the count.

Example: If one arrangement has \bullet\bullet\bullet (3 bindis), write 3\mathbf{3}.

(Note: The exact numbers depend on the printed bindi arrangements in the image. Use the counting method above for each arrangement.)

Final Answer: Write the number that matches the count of red bindis in each arrangement.
DPlay with your friend. Roll the dice and colour a box with the same number of dots as on the dice. Take turns with your friend and roll again. The child with more number of coloured boxes will win.Show solution
Given: This is a two-player dice game activity.

Concept: Match the number of dots on the dice to the number on the grid and colour the corresponding box.

How to play:
1. Choose your colour and your friend chooses a different colour. Fill in the colour boxes provided.
2. Roll the dice. Count the dots on the top face of the dice.
3. Find the box on the grid that shows that number and colour it with your colour.
4. Your friend rolls the dice and colours a box with their colour.
5. Keep taking turns until all boxes are coloured.
6. At the end, count how many boxes each player has coloured.

Final Answer: The player who has coloured more boxes wins the game. This activity helps in recognising numbers 11 to 66 instantly (subitization).

Vanishing Buttons — Zero Concept

Story ActivityWrite the number of birds sitting on the branch of the tree. (A series of tree images is shown with different numbers of birds.)Show solution
Given: Several images of trees with birds sitting on branches are shown.

Concept: Count the birds on each branch carefully and write the number.

Working:
- Look at each tree image one by one.
- Count every bird sitting on the branch.
- Write the number below or beside each image.

Example sequence (based on the vanishing/reducing pattern of the story):
- Image 1: 44 birds
- Image 2: 33 birds
- Image 3: 22 birds
- Image 4: 11 bird
- Image 5: 00 birds

(Note: Count the birds in each picture carefully. The number may go from a higher number down to zero, just like the buttons in the Gola monkey story.)

Final Answer: Write the counted number of birds for each image. Remember, if no birds are sitting, the answer is 0\mathbf{0} (Zero).
Think and Tell AHow many suns do you see in the night?Show solution
Given: We are asked about the number of suns visible at night.

Concept: The Sun is not visible at night because it is on the other side of the Earth.

Answer: We see 0\mathbf{0} (Zero) suns in the night.

This is an example of zero — when something is completely absent, its count is zero.
Think and Tell BHow many moons do you see at noon?Show solution
Given: We are asked about the number of moons visible at noon (daytime).

Concept: The Moon is generally not visible during the day (at noon) because the bright sunlight makes it very hard to see.

Answer: We see 0\mathbf{0} (Zero) moons at noon.

This again shows the concept of zero — the count of something that is not present or not visible is zero.

Tenth Birthday — Counting to 10

Count and WriteShe has lighted diyas on her birthday. Count and write the number of objects: Beads, Laddoos, Crayons, Bananas, Leaves.Show solution
Given: Images of beads, laddoos, crayons, bananas, and leaves are shown.

Concept: Count each group of objects carefully and write the total number. All groups should total 1010 as the theme is Aastha's 10th birthday.

Working:
- Beads: Count each bead on the string → 10\mathbf{10}
- Laddoos: Count each laddoo → 10\mathbf{10}
- Crayons: Count each crayon → 10\mathbf{10}
- Bananas: Count each banana → 10\mathbf{10}
- Leaves: Count each leaf → 10\mathbf{10}

Final Answer:
Beads=10,Laddoos=10,Crayons=10,Bananas=10,Leaves=10\text{Beads} = 10, \quad \text{Laddoos} = 10, \quad \text{Crayons} = 10, \quad \text{Bananas} = 10, \quad \text{Leaves} = 10

Let us Do — Making 10

ACount and draw beads to make a string of 10 beads. (Four strings with some beads already drawn are shown.)Show solution
Given: Four bead strings are shown, each with some beads already drawn. We need to add more beads to make each string have 1010 beads total.

Concept: 1010 is the target. Count the beads already on the string, then draw the remaining beads.

Formula: Beads to draw == 1010 - Beads already on string.

Working (general method for each string):
- String 1: If 77 beads are drawn, draw 107=310 - 7 = 3 more beads.
- String 2: If 55 beads are drawn, draw 105=510 - 5 = 5 more beads.
- String 3: If 88 beads are drawn, draw 108=210 - 8 = 2 more beads.
- String 4: If 66 beads are drawn, draw 106=410 - 6 = 4 more beads.

(Note: Count the beads in each printed string and draw the exact number needed to reach 1010.)

Final Answer: Each completed string must have exactly 10\mathbf{10} beads.
BDraw buttons to make a ten frame of buttons. (Five ten-frames with some buttons already drawn are shown.)Show solution
Given: Five ten-frames are shown, each with some buttons already placed. A ten-frame has 1010 boxes in total (22 rows of 55).

Concept: A ten-frame holds exactly 1010 objects. Count the empty boxes and draw a button in each empty box.

Formula: Buttons to draw == 1010 - Buttons already in frame.

Working (general method):
- Frame 1: If 33 buttons are placed, draw 103=710 - 3 = 7 more buttons.
- Frame 2: If 66 buttons are placed, draw 106=410 - 6 = 4 more buttons.
- Frame 3: If 44 buttons are placed, draw 104=610 - 4 = 6 more buttons.
- Frame 4: If 88 buttons are placed, draw 108=210 - 8 = 2 more buttons.
- Frame 5: If 99 buttons are placed, draw 109=110 - 9 = 1 more button.

(Note: Count the buttons already in each frame and fill the remaining empty boxes.)

Final Answer: Each ten-frame must be completely filled with 10\mathbf{10} buttons.

The Handy Five and Ten — Number Pairs

Pattern ActivityFollow the pattern and write the number pairs separated by the stick (number pairs of 5).Show solution
Given: A pattern of number pairs that add up to 55 is shown using finger images.

Concept: Two numbers that together make 55 are called number pairs of 55.

Working — All pairs of 55:
0+5=50 + 5 = 5
1+4=51 + 4 = 5
2+3=52 + 3 = 5
3+2=53 + 2 = 5
4+1=54 + 1 = 5
5+0=55 + 0 = 5

Final Answer: The number pairs of 55 are: (0,5), (1,4), (2,3), (3,2), (4,1), (5,0)(0,5),\ (1,4),\ (2,3),\ (3,2),\ (4,1),\ (5,0).
Let us PlayShow 3 fingers. Your friend has to show some fingers to make it 5.Show solution
Given: One child shows 33 fingers.

Concept: We need to find how many more fingers make 55.

Working:
3+?=53 + ? = 5
?=53=2? = 5 - 3 = 2

Final Answer: The friend has to show 2\mathbf{2} fingers to make it 55.

Number Pairs of 10

Pattern ActivityFollow the pattern and write the number pairs in the given table (number pairs of 10, using the finger game with both hands).Show solution
Given: A finger game is played where one child shows some fingers and the other shows the remaining fingers to make 1010.

Concept: Two numbers that together make 1010 are called number pairs of 1010.

Working — All pairs of 1010:
0+10=100 + 10 = 10
1+9=101 + 9 = 10
2+8=102 + 8 = 10

Concept: Count the full group of 1010 first, then count the extra ones and add them.

Working (general method):
- Count the objects in the full box/group: that gives 1010.
- Count the remaining loose objects: that gives the units.
- Add: 10+10 + units == the total number.

Example: If there is 11 full group of 1010 and 33 extra objects:
10+3=1310 + 3 = 13

Final Answer: Write the total count for each image using the method above.
BColour the tens frames to show the number. (Numbers between 11 and 20 are given; two ten-frames are shown for each number.)Show solution
Given: A number (between 1111 and 2020) is given. Two ten-frames are provided — one full frame (for the tens) and one partial frame (for the units).

Concept: Numbers 11112020 have 11 ten and some units. Colour 1010 boxes in the first frame and the remaining units in the second frame.

Working (example for 1414):
- 14=10+414 = 10 + 4
- Colour all 1010 boxes in the first ten-frame.
- Colour 44 boxes in the second ten-frame.

General rule for any number NN where 11N2011 \leq N \leq 20:
- First ten-frame: colour all 1010 boxes.
- Second ten-frame: colour N10N - 10 boxes.

Final Answer: Colour the ten-frames according to the number given, always filling the first frame completely and the second frame partially.
CWrite down the numbers in sequence. (Two sequences with missing numbers are shown.)Show solution
Given: Two number sequences with some numbers missing are shown.

Concept: Numbers from 11 to 2020 follow a fixed order. Each number is 11 more than the previous number.

Working:

- Sequence 2 (example): 16,_,18,19,_16, \_, 18, 19, \_ → Missing numbers =17= 17 and 2020

(Note: Fill in the blanks by identifying which numbers are missing from the sequence 11 to 2020.)

Final Answer: Write the missing numbers so that the sequence is in the correct order from smallest to largest.
DEncircle a group of ten in the pictures and match with the number.Show solution
Given: Pictures with objects (more than 1010) are shown alongside numbers.

Concept: To count objects beyond 1010, first circle a group of 1010, then count the remaining ones and add.

Working:
- Look at the picture and draw a circle around any 1010 objects.
- Count the objects left outside the circle.
- Total =10+= 10 + remaining objects.
- Draw a line to match the picture with the correct number on the right.

Example: If a picture has 1010 circled +3+ 3 remaining =13= 13, match it to 1313.

Final Answer: Circle the group of 1010 in each picture and draw a matching line to the correct number.
