About this resource
If you are looking for engaging maths games for your lower secondary students to complete, I have just the resource for you. If your students are learning about or have mastered ratios, this is a Ratio Monster Puzzle that they will enjoy. This activity is great for 6th – Year 9 students. The objective of the game is for students to correctly draw and colour their monster based on the given descriptions.
This is a 1-page printable that features an incomplete monster for students to complete. At the top of the page, there are 8 different descriptions for students to read and complete. An example of the descriptions is he has 2 legs compared to his 5 limbs and his ratio of horns to green spots is 3 to 4.
At the bottom of the page, students will be prompted to finish colouring the monster however they choose. Students will need to add at least 3 new characteristics, while keeping the above ratios true. They can compare 5 things of their own choosing. They should have 2 part-to-part ratios compared to their 5 comparisons. Students will be given the challenge of using all three types of ratio representations as seen above.
I hope you enjoy!

Teaching tips & learning objectives
Learning objectives
Interpret ratio statements written in different notations (colon, 'compared to,' and 'to' phrasing) to determine a quantity relationship.
Apply given ratios to create an accurate drawing that satisfies every stated ratio relationship.
Generate original part-to-part ratio comparisons that remain consistent with previously established ratios.
Teaching tips
Use as a creative, low-stakes check for understanding after introducing ratio language and part-to-part ratios.
Have students trade finished monsters with a partner and verify that the partner's drawing actually satisfies all 8 given ratios.
Assign the challenge extension (using all three ratio-representation styles) only to students who have already mastered writing ratios in a single notation.
Skills covered
Ratio interpretation — students read 8 ratio statements (e.g. 'arms to eyes ratio is 3:1') and translate them into a specific number of drawn features.
Ratio notation flexibility — students encounter and are challenged to reuse three different ways of expressing a ratio: colon notation, 'compared to' phrasing, and 'to' phrasing.
Part-to-part ratio construction — students write their own original ratio comparisons, with at least 2 required to be part-to-part.
