The author used this set for three activities: (a) students mimic each problems using coins; (b) students illustrate each problem by drawing circles; (b) students create mathematical model for each problem.
Mimicking events from a problem with a teacher’s guidance helps students understand vocabulary and find the answer.
The materials needed: problem’s text, pencil, 10 coins, paper, and 2 big erasers, one with the letter A on it while the second with the letter B.
After children understand a problem, they illustrate it with a picture and are therefore able to solve it using one-by-one counting of the coins or circles in the illustration.
Based on the pictorial models and answers, students create number sentences.
