Division 7 students have enjoyed taking part in our Counting Collection activities. The children have enjoyed applying their mathematical thinking to count different materials and objects. This hands-on experience has been a great introduction to our Multiplication Unit.
What are some concepts we practice during counting collection time?
- one-to-one correspondence
- cardinality – knowing the last number stated when counting represents the total
- stable order
- subitizing
- estimating
- place value (e.g., teens as ten and some more, 2-digit numbers as groups of tens and ones, etc.)
- connecting a count to a numeral
- skip counting
- multiplicative thinking (e.g., I have five groups of seven and three more)
- division (and how this is related to multiplication)
- flexible counting strategies
- factors and multiples – which can lead to discussions about prime and composite numbers
Estimation + Counting Strategies:
We started off by estimating how many items were in each bag. We then had to figure out different strategies to find the answer. We counted by 1`s, 2`s , 3`s, 5`s and 10`s
Introduction to equal groups in multiplication:
Students used their counting collections to make equal groups. We discussed the link between multiplcation and counting strategies.
