31. FINAL JEOPARDY Mrs. Jones told her class that they could calcuate the difference between 20 x 2 and 20 x 3 without doing any multiplication. Show how Mrs. Jones’ class might have solved the problem. You can use pictures, arrays, number models, diagrams, coins or counters.

32. Final Jeopardy 20 x 2 and 30 x 2 20 + 20 = 40 20 + 20 + 20 = 60 60 – 40 = 20 I know that multiplication is repeated addition so 20 x 2 is the same as 20 + 20 and 20 x 3 is the same as 20 + 20 + 20. 60 – 40 = 20, so the difference is 20!
