Question

m6|l3 reasoning about contexts with strip diagrams (part 2)
write an equation to represent the diagram.
strip diagram with four parts: 6, y, y, y, total 30
□ = □ + □ + □ + □
below: 30, y, 6 (as tiles)

Explanation:

Step1: Identify total and components

The total length of the strip is 30, made up of 6 and three segments of $y$.

Step2: Assemble the equation

Match the total to the sum of its parts.
$30 = 6 + y + y + y$

Answer:

$30 = 6 + y + y + y$
