Chapter 8 Number Sense

I agree with Van De Walle, J. (2009,p29) that he mentioned “Children continue to develop number sense as they begin to use numbers in operations, build an understanding of place value, and devise flexible methods of computing and making estimates involving large numbers, fractions, decimals, and percents.” Now I know why our curriculum taught K2 children up to number 20. Most parent question us why do we stop at 20. Though we know that children will acquire it when they moved on, now I found the evidence and reasons behind it.

As mentioned in the text, soon after children learned number 1-20, it has moved quickly to addition and subtraction instead of  more exposure to other number operations. Hence I am determined to make the children learn mathematics in the proper ways it should - the CPA Approach
