What to Focus On

  • People first counted by marks on walls and tree bark.
  • Groups of 5, 10, 20, and 60 were used to keep records.
  • Only ten symbols are needed to write any number.
  • 100 can be made by adding two parts.
  • A number line helps show jumps that complete 100.
  • Bundles and loose sticks help show place value.
  • 100 can be joined with ones to make new numbers.
  • 101 means 100 and 1.
  • 102 means 100 and 2.

Common Mistakes to Avoid

Clap means 10, snap means 100, and pat means 1.

Talking Pot says the same number back, not one more.

100 and 1 is called 110 because the 1 is added to 100.

Memory Tips

Zero means nothing and helps number writing work

Ancient Indians used ten symbols 0 to 9

The number system is used everywhere in every country
