Written by Adi Ackerman, Head Teacher
"Two-Step Equation Number Chain" is written for 7th Grade (Ages 12-13), and it covers Common Core 7.EE.B.4.A. A 6th grader who is already steady on math puzzles can use it too, and an older student can use it as a short review.
7th grade math worksheet: solve a chain of eight two-step equations, copying each solution into the next one, to end at −7. Answer key included. Part of our number puzzles collection. Aligned to Common Core standards.
How do I use this worksheet?
Choose by skill, such as ladders for integer sums or equation puzzles for algebra. The partner game works well for a pair or a small group.
What students will practice
- Students will solve two-step equations such as 4x + 5 = −3.

Common Core State Standards
Expressions and Equations · 7th Grade
Standard: Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.

What does this worksheet teach?
⌄
Solve a chain of eight two-step equations, copying each solution into the next one, to end at −7. The directions on the page read: Solve equation 1. Copy its solution into the box in equation 2, then solve. Follow the arrows to equation 8. If every link is right, equation 8 has the solution −7. An answer key is included.
Can I use this number puzzles worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade math puzzles, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What are number puzzles?
⌄
Puzzles where the numbers follow a pattern or rule, such as ladders, pyramids and magic squares.
What skills do they cover?
⌄
Integer and decimal sums, signed fraction products and quotients, and two-step equations, plus a coordinate reflection picture and a nonogram.
Do they have answer keys?
⌄
15 of the 16 do. The Signed Number Dots and Boxes Game is a partner game and has none.
