Catch a Pokémon right in your math class! Collaborative motivation meets individual accountability in this highly engaging linear systems word problems / applications colouring task! Each student's worksheet represents a small section of the large Pikachu.

3 different mosaic sizes are included, to accommodate different class sizes. (12, 16, and 24 sheet mosaics are included.)

**2021 Update: Google Sheets DIGITAL mosaic version for all three sizes now included! **

DOWNLOAD THE PRODUCT PREVIEW to see exactly what type of problems students will be solving! (the TpT preview window is slow displaying the images, so downloading works better)

Students solve a rich variety real-world and mathematical problems leading to two linear equations in two variables. Problems involve motion, mixtures, investments, money and value, etc.

This task lends itself perfectly to small-groups, since each worksheet is different but structurally similar. Expect to overhear some rich mathematical dialog taking place! This is a challenging assignment, but the collaborative reward will drive them to the end goal.

Leave the picture a secret or share it for motivation… it’s your call!

INCLUDED (.pdf and .docx everything):

• Complete class sets of worksheets for the 12, 16, and 24 sheet mosaics

• Exemplar Solutions for every type of problem contained on students' worksheets. Post this, or use it for examples during your lesson!

• TEACHING TIPS page for smooth implementation of this product

• Complete answer keys for all worksheets

• Completed coloured mosaic guide with coordinates to help you assemble the finished product


• Each worksheet contains twelve assorted linear systems word problems

• Each worksheet contain a randomized answer list at the bottom, allowing students to check their answers before colouring.

• All problems have (or round to) integer solutions for the two variables, although percentages, decimals or fractions may be involved in the process of solving.

If you like this product, be sure the check out the whole Collaborative Math Mosaic directory, sorted by topic!

All my “Colouring by…” worksheets use standard pencil-crayon colours found in the Crayola 24 pack. For best results, use the exact colour name match, and have all student use the same colouring medium. Perhaps a class set of pencil crayons would be a fun math department investment!

to see state-specific standards (only available in the US).
Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.
Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or non-viable options in a modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods.
Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
Create equations and inequalities in one variable and use them to solve problems.
