Grade 1 Math
Number
7. Demonstrate how a given number can be represented by equal groups with and without singles
7.2 Groups and arrays up to 10
Groups and Arrays up to 10
See how a math array of rows and columns and a set of equal groups both lead to the same multiplication fact, using totals up to 10.
What You'll Learn
Identify an array as objects arranged in equal rows and columns, unlike loosely arranged equal groups
Apply the idea \( rows \times columns = total \) to find how many objects are inside an array
Compare an equal-groups picture and an array that both show the same total, such as \(10\)
Recognize that adding a row repeatedly, such as \(5+5=10\), matches the multiplication \(2\times5\)
Build arrays with a total up to \(10\) to practice rows-times-columns thinking before larger totals
What You'll Practice
1
Counting dots arranged in arrays and identifying rows and columns
2
Matching diagrams to statements about groups and totals
3
Writing number sentences that describe array arrangements
4
Selecting arrays that match given group descriptions
Why This Matters
Understanding groups and arrays builds your foundation for multiplication and division. This visual way of organizing numbers helps you solve real-world problems like arranging items in boxes, understanding egg cartons, or organizing seating charts.
