# Show Me the Number

Keywords:
Purpose:

The purpose of this activity is to develop students’ ability to show two-digit numbers using place value material.

Specific Learning Outcomes:

show two-digit numbers using place value material.

Required Resource Materials:
Sticks and rubber bands
Counters and small canisters
Activity:

Provide students with one of the types of equipment listed, for example sticks and rubber bands.

1. Write a two digit number on the board, for example, 28.
2. Ask each student to count out 28 sticks.
How many groups of ten do you think you can make?
How many will you have left over?
4. Have students count the sticks into groups of ten and bundle these together with rubber bands.
How many groups of ten did you make?
How many do you have left over?
6. Link the numbers of tens and ones back to the written numeral. We have 2 tens (pointing to the 2 in the number 28) and three ones left over (pointing to the 8 in the number 28).
7. Repeat with other 2 digit numbers and using a variety of equipment types.

## Checking Addition and Subtraction by Estimation

Solve addition and subtraction problems by using place value.

## Tens in Hundreds and More

Recall the number of tens and hundreds in 100s and 1000s.

Recall groupings of twos, threes, fives, and tens that are in numbers to 100 and the resulting remainders.

Find out how many ones, tens, hundreds and thousands are in all of a whole number.

Find the number of tenths, hundredths, and one–thousandths in numbers of up to three decimal places.

## Zap

Recall the number of 10s within decades and decades that add to 100.

Recall groupings within 100.

Find out how many ones, tens, hundreds and thousands are in all of a whole number.

Know what happens when a number is multiplied or divided by a power of 10.

## Nudge

Say the forwards and backwards number word sequences by ones, tens, and hundreds in the range 0 – 1000.

Say the forwards and backwards whole number word sequences by ones, tens, hundreds, and thousands in the range 0–1 000 000, including finding numbers that are 10, 100, and 1 000 more or less than a given number.

Say the number one–thousandth, one–hundredth, one–tenth, one, and ten, etc, before and after any given number.

## Using Calculators

Say the forwards and backwards number word sequences in the range 0–100.

Say the forwards and backwards skip–counting sequences in the range 0–100 for twos, fives, and tens.

Say the forwards and backwards number word sequences by ones, tens, and hundreds in the range 0 – 1000.

Say the forwards and backwards whole number word sequences by ones, tens, hundreds, and thousands in the range 0–1 000 000, including finding numbers that are 10, 100, and 1 000 more or less than a given number.

Find out how many ones, tens, hundreds and thousands are in all of a whole number.

Say the number one–thousandth, one–hundredth, one–tenth, one, and ten, etc, before and after any given number.
