Building Arrays
Materials: number cubes, counters
______________________________________________________________________________- Roll a number cube twice. The first number you roll tells how many
rows to make in your array. The second number you roll tells how many
counters to put in each row of your array. - Draw the array and write an equation to express the total number of
counters as a sum of equal addends. - Write a multiplication equation to represent your array.
Example: Lisa rolls a 2 first and then a 5. She makes an array with 2 rows of 5.- Build and record ten different arrays.
2 rows of 5
5 + 5 = 10
2 x 5 = 10
