4th Grade - Multiplication

Next week, our fourth graders will continue their study of multiplication. We are espcially using the idea that you can multiply by 10 to solve a 2-digit problem. For example, to solve 15 x 13, students can think of the number 13 as 10 + 3. So, instead of 13 groups of 15, there are 10 groups of 15 and 3 groups of 15. 10 groups of 15 = 150 and 3 groups of 15 = 45. Add 150 + 45 to get your answer of 195.

4th Graders will also take a test next week on thier multiplication combinations. It is expected that students should be able to solve 30 problems (1-digit x 1-digit) in 3 minutes. Students who do not meet this expectation should continue to study thier combination cards at home.
