Teach Grade 2 students equal groups and arrays with fun printable worksheets, repeated addition practice, early multiplication activities, and engaging visual math exercises for classroom or homeschool learning.
Equal Groups & Arrays Practice
0 / 7
Try these before or after you print the worksheet. An array shows things in equal rows. You can add the rows up or count the dots — both give the same answer, and seeing why is the whole idea.
Question 1
How many dots are in this array?
12. There are 3 rows with 4 in each row, so it is 4 + 4 + 4 = 12. Adding 3 and 4 would give 7 — but the rows are not being joined end to end, they are being repeated.
Question 2
Which addition matches this array?
3 + 3 + 3 + 3 = 12. 4 rows, 3 in each row, so you add 3 four times. Writing 4 + 4 + 4 would be three rows of four — the same total here, but it is not what the picture shows.
Question 3 — select all that apply
Select every addition that equals 12, then press Check.
3 + 3 + 3 + 3; 4 + 4 + 4; 6 + 6 all make 12. Three different arrays, same total: 4 rows of 3, 3 rows of 4, and 2 rows of 6.
Question 4 — put them in order
Click these in order, from the smallest total to the largest.
2 groups of 3 = 6 < 3 groups of 3 = 9 < 2 groups of 5 = 10 < 3 groups of 5 = 15. Work each one out before comparing: more groups does not always mean a bigger total.
Question 5
A garden has 5 rows of flowers. Each row has 4 flowers. How many flowers in all?
20 flowers. 5 rows with 4 in each: 4 + 4 + 4 + 4 + 4 = 20. The rows are equal, which is what makes it an array.
Question 6 — challenge
4 groups of how many make 16?
4. Going backwards: you need four equal groups adding to 16, and 4 + 4 + 4 + 4 = 16. This is the same question as 16 shared into 4 equal rows.
Question 7 — spot the mistake
A student says: “3 rows of 4 and 4 rows of 3 must give different totals, because the arrays look different.” What went wrong?
Both make 12. The pictures are different shapes but there are the same number of dots — turning an array on its side rearranges it without adding or removing anything.
Think about it
4 rows of 3 and 3 rows of 4 both make 12. Will swapping the rows and columns always give the same total?
Why is 5 + 5 + 5 quicker to work out than counting fifteen dots one at a time?
How many 2s make 14? How did you work it out — counting up, or something faster?
Could you draw an array for 7 that has more than one row? What does that tell you about 7?
