Homework

Great job this week 5th graders. Thank you for working so hard and being responsible!

Math: We have a quiz on the distributive property on Monday. Here is the practice problem that you requested.


Can you use the distributive property to solve 69 X 72

Draw an open array and then show how you broke up the problem.

Next write the problem mathematically showing how the d. property works.

For example: 23 X45 = (20 + 3) (40 +5) = (20 X 40) +(20 X 5) + (3 X 40) +(3 X 5)=1,035
