Math One Step Equations Activity Worksheet by Teach Simple

About this resource

What's inside this resource

Eight one-step equations — covering addition, subtraction, multiplication, division, and a proportion, such as 10x = 50 and 3/4 = n/16 — are each labeled with a letter that doubles as a decoding key for a hidden message. Students solve each equation and match the numeric answer to a blank in two answer strips beneath the equations, spelling out the phrase "I think I can" once every equation is solved correctly. The file lays the equations out in two columns, with a worked-answer version showing the correct value beside each letter and the completed message spelled out. The letter-decoding format lets students confirm their own work, since an incorrect solution produces a message that does not read correctly and signals a mistake to revisit.

Teaching tips & learning objectives

Learning objectives

Solve one-step addition and subtraction equations for an unknown variable
Solve one-step multiplication and division equations for an unknown variable
Solve a one-step proportion equation involving fractions

Teaching tips

Have students solve independently first, then reveal the message as a class to self-check their equation-solving accuracy.
Since the file is labeled editable, adjust the equation values or message to create a fresh version for retests.
Use as a fast-finisher or homework activity, since it only requires eight short equations.

Skills covered

Solving one-step equations — students isolate the variable in equations involving addition, subtraction, multiplication, and division, e.g., -9 = r - 16 and 5m = 95.
Solving proportion equations — students solve 3/4 = n/16 using cross-multiplication or equivalent fractions.
Self-checking via decoding — students use their solved values to spell out a hidden message, which confirms accuracy through the puzzle format.
