Activity 01
Manipulative Arrays: Build and Count
Provide counters or buttons. Students form arrays for facts like 2 x 5 by making two rows of five. They sketch the array, write the repeated addition, and state the product. Switch partners to verify.
Compare multiplication as repeated addition versus multiplication as equal groups.
Facilitation TipDuring Manipulative Arrays, circulate and ask each pair to explain how many rows and columns they built and how they counted the total.
What to look forProvide students with small counters or blocks. Ask them to build an array for 3 x 5. Then, ask them to write the repeated addition sentence that matches this array. Observe if they correctly form the array and write the addition sentence.
