Counting & Cardinality
5. Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.
This lesson is pretty easy to set up. Place 20 blocks in a line, rectangular array or a circle and then ask students “How many blocks are here?” Have students count the blocks and give an answer. Have 10 blocks in a scattered configuration, give them a number from 1 – 20 and have them count the amount using blocks on the screen.
