About this worksheet

Evaluating expressions and formulas. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can put a number in for a letter and work out the value: 3x with x = 4 is 12.
I can still multiply before I add, and do the power before the multiplying, after I put the number in.
I can use a formula such as A = lw or P = 2(l + w).

Standard: 6.EE.A.2c

Words to know

evaluate: Find the value of an expression when each letter is replaced by a number.

substitute: Put a number in the place of a letter.

formula: A rule written with letters, like A = lw for the area of a rectangle.

squared, cubed: Squared means times itself (s²). Cubed means three copies multiplied (s³).

parentheses: Marks round a part that must be worked out first.

Common mistakes

Your child put the number and the value side by side (3x with x = 4 as 34). Try asking "3x means 3 groups of x. If x is 4, what is 3 groups of 4?"

Your child added or subtracted before multiplying after putting in the number (2 + 3x with x = 4 as 5 × 4). Try asking "which part is multiplied, and what does that give before we add the other number?"

Your child doubled instead of squaring (5² as 10). Try asking "5² means 5 groups of 5. How many is that?"
