The Ones that make up the Tens!! Activity @ ELP3 CPSGS TMZ

Written by admin

To understand place value children need to understand the principle of exchange – one of these is equal to ten of those. Providing children with concrete experiences of exchange will help them learn and establish this principle. Math games help children to understand the concept of Tens and Ones easily. The version of this game uses pistachio shells, colour papers and glue. The facilitators drew up a template on a colour paper with two columns, one each for Tens and Ones. Each kid was given a few pistachio shells to do the counting. A set of two digit numbers was given to each child. The children were amazed to find that they didn’t have to count by 1’s to make those two digit numbers. For example for the number 47, all they had to do was place 4 of the shells in the Tens column to make forty, followed by seven shells in the Ones column. When they finished making up their numbers using counters, they counted from the bundles of ten (e.g. 10, 20, 30, 40), then ones (1, 2, 3, 4, 5, 6, 7) to make sure their counters matched the numbers given to them. With time and practice, they will see ten as a unit made of 10 ones and will be able to use tens as a unit to count. This is a useful mathematical strategy, as counting by tens is much quicker than counting by ones.
