Students will find multiplication patterns by skip counting on the hundreds chart starting with 2s and working through the 12s. Students will also use arrays to help them to visualize and find solutions to multiplication and division problems. Examples of arrays are pictured below. 4x3=12 3x6=18 4x4=16  They will also begin solving multiplication problems using cluster problems. These problems allow students to solve a more difficult problem by relating it to a known fact. Example: If a child knows 3x3=9, they can double their answer to find the product for 6x3=18, and in turn double that answer to find the product for 12x3=36. They can also break more difficult problems into more manageable parts using clusters. Example: 32 x 5 = 160 This problem can be broken up into 2 smaller problems such as: (30x5)+ (2x5) = 160  30 2  5 = 160 Other students may feel more comfortable separating the above problem in this way: (10x5)+(10x5)+(10x5) +(2x5) = 160  10 10 10 2 5 = 160 You can help at home in the following ways: Practice multiplication and division facts for 10 minutes each night Help your child practice skip counting by 3s, 4s, 5s and so forth Play the array games that your child brings home for homework Ask your child to explain their thinking as they solve problems As always, thank you for your continued support and hard work at home!
