Sample Additional Practice Exercise 1

Draw counters to show how to make 3. Then write an equation to match the counters. A mat shows 1 counter on the left and 2 counters on the right. The equation 1 plus 2 equals 3 is written.

Draw a counter in the left part of a mat to show 1. Two more counters are needed to make 3 in all. So, draw 2 counters in the right part of a mat. Complete the equation: $1 + 2 = 3$ .
