reSolve: Multiplication: Trays of Arrays
TLF ID A004853
This sequence of 7 tasks uses the array to explore the distributive and associative properties of multiplication. Students use different strategies to calculate the number of items in arrays, and use mathematical reasoning to explain which strategies are the most useful. Students learn to use the distributive property to partition and distribute factors, and the associative property to group numbers to form known facts. Professional learning for teachers is integrated throughout the sequence.
