Reply To: Lesson 4-1: From Spatial to Counting Comparisons – Discussion

[Jeanette Cox]

On the tray place the teddy bear counters and the tiles. Which is more and which is less? How do you know? First by direct visual comparing and then counting using one to one correspondence and cardinality that the last number said represents the quantity. The direct measure is placing each object under a dot and then saying the last number named as the indirect measure of the numeral 4. Heirarchial inclusion can be seen as two red and one yellow and one green are the same as four. The dots provide a number path leading to using a numberline.
