Place Value Cards

Australian curriculum number (ACMNA026; ACMNA027; ACMNA028)

This sequence explores the multiplicative place value properties of numbers. Students learn to represent numbers up to 1000 as multiples of 100s, 10s and 1s. For example, 664 = (6 x 100) + (6 x 10) + (4 x 1).

This sequence is for students who:

  • have a sound understanding of the additive place value of numbers, that is, 64 is made up of 60 and 4.
  • have experience skip counting off the decade by 10s and 100s.  

 

Lesson 1: Counting Cards

The teacher uses a set of cards with 1, 10 and 100 and asks students to skip count according to the numbers on the cards. The cards are shuffled and then recounted. Students are asked to consider why they reach the same total when the cards are presented in a different order. They then explore the relationship between the cards and the place value property of the final number in the count.

Lesson 2: Counting With Plato

Students look at the fact that counting 10 ones is equal to 10, 10 tens is 100 and 10 hundreds is 1000. Plato the Counting robot is introduced to the students. The students count with Plato and then, using the total of the count, reflect on how many 1s, 10s or 100s may have been shown in the counting sequence.
