Choose all answers that are correct.
A.Draw a diagram.
Draw 2 squares and 5 circles. Then draw 3 squares and 4 circles. Add the total number of squares and circles.
B.Use logical reasoning.
Think that finding 2 groups of 5 is the same as 2 × 5 = 10 and that 3 groups of 4 is the same as 3 × 4 = 12. Then add 10 + 12.
C.Model the problem.
Show 2 groups of 5 chips and 3 groups of 4 chips. Then count all the chips.
