Why Zero Matters in a Two-Digit Number

Name:                              
Date:              

Today I am practising: interpreting zero ones in a multiple of ten

1

Write the numeral for 4 tens and 0 ones.

2

Compare 6 and 60. Draw a representation of each.

3

A learner writes 7 for 7 tens and no loose ones. Correct the numeral and explain.

4

Complete 80 = ___ tens + ___ ones.

5

Write the multiple of ten between 30 and 50.

6

Choose 20 or 2 to represent two bundles of ten. Explain what zero records.

Grown-up guide
  1. Keep an empty ones column visible beside the tens.
  2. Avoid describing zero as meaningless; it identifies the empty place.
  3. Read the numeral aloud after the learner builds it.
