Use this creative practice to foster skills with whole numbers, decimals, and integers and to develop rich number sense. Students will find countless patterns in this activity which will help them to master and solve the puzzles as they use critical thinking, proportional reasoning and develop algebraic skills. Comprehensive and detailed instructions and three activity masters are included along with answer keys and a blank template to create even more worksheets.

Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
Solve real-world and mathematical problems leading to two linear equations in two variables. For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.
Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.
Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation “Subtract 𝘺 from 5” as 5 - 𝘺.
