What to Focus On

  • Counting by tens helps in large numbers.
  • 200 and 50 more means 250.
  • 200 and 80 more means 280.
  • One number can have more than one number sentence.
  • 200 + 35 and 250 - 15 both show 235.
  • 211 has 2 hundreds, 1 ten, and 1 one.
  • A number line shows order.
  • 235 lies between 200 and 250.
  • Number lines help compare numbers and find distance.

Common Mistakes to Avoid

When comparing two 3-digit numbers, all digits must be checked one by one from left to right, even if the hundreds digits are different.

If the hundreds digits are the same, the ones digit always decides the answer first.

The total toffees are only the ones in the boxes, so the 2 toffees in Jojo’s hand should not be counted.

Memory Tips

Counting triangular torans to 250

Counting bangles to 280

Total toffees = 300

Open mouth points to the bigger number
