Blueprint Key: How to Draw a Grid
Grids are math blueprints! Read the dimensions, then shade the blocks. Count the Rows (going down) first, and the Columns (going across) second. Multiply them to find the total block count.
2 Rows
× 4 Cols
= Draw Me!
Section A: Grid Drafting Practice
Shade the correct number of rows and columns on the blank blueprint grids, then complete the multiplication equations.
01 Shade Array: 3 × 5
How many rows?
Blocks in each row?
Equation: 3 × 5 =
02 Shade Array: 2 × 10
How many rows?
Blocks in each row?
Equation: 2 × 10 =
03 Shade Array: 5 × 2
How many rows?
Blocks in each row?
Equation: 5 × 2 =
04 Shade Array: 1 × 6
How many rows?
Blocks in each row?
Equation: 1 × 6 =

Use inverse relationships to solve division using blueprints
Deconstruction Guide: Grid Division
Division is the opposite of multiplication. Start with the Total Blocks, divide them by the number of Rows, and you will find the number of Columns!
6 Total
÷ 2 Rows
= 3 Cols
Section B: Grid Deconstruction Practice
Solve these division equations by shading or analyzing the blank blueprint outlines.
05 Shade Total: 15
Total Blocks: 15
Rows (down): 3
Columns: 15 ÷ 3 =
06 Shade Total: 30
Total Blocks: 30
Rows (down): 3
Columns: 30 ÷ 3 =
07 Shade Total: 10
Total Blocks: 10
Rows (down): 2
Columns: 10 ÷ 2 =
08 Shade Total: 8
Total Blocks: 8
Rows (down): 1
Columns: 8 ÷ 1 =
Section C: Grid Master Challenge
Challenge Problem:
Builder Ben is installing solar panels. He lays down 5 rows of solar panels, with 4 panels in each row.
➔ Shade his grid on the blueprint array to the right.
Write his math blueprint formulas:
5 × 4 = 20 ÷ 5 =
