Riddle Books and Common Core

Riddle Books teaches Common Core-aligned pre-algebra concepts via story problems in a friendly game-based environment. All grades and all levels are invited to participate in the Washington state challenge, designed to enable any learner to solve story problems both at and beyond their grade level. Get started and plan your classroom week with Riddle Books!

Riddle Books features linear progression with some adaptivity!

Every student will progress through each of the problem types. Older students will likely progress more quickly although it may take them a while to master setting up the models (this is both the fun and the challenge for many of the problems).

If a student masters a problem type, they will be moved on but will occasionally get a review question both for practice and to ensure they are not simply applying the same pattern repeatedly.

If a student struggles for success with a particular problem type, they will sometimes be moved to previous material to help bolster success and sometime moved on to newer material in order to provide variety.

Teacher Feedback

The live dashboard in the Teacher Copilot gives feedback in two ways by showing both progress (number of problems attempted) and proficiency (correctness of problems attempted). The cumulative dashboard shows number of problems solved of each type and total time spent on task.

The leaderboard shows how your class is doing against all of Washington State. Challenge your colleagues! A little friendly competition never hurts!

Meet the Problem Types

There are seven problem types that your students may encounter in Riddle Books. Within each type there are several sub-types depending on what value(s) is missing and what value(s) is known. Click on each category headline below to jump to a visual demonstration of each type, or watch our YouTube playlist featuring all seven!

Fundamental

Common Core: K.OA.2, 1.OA.1, 1.OA.2, 2.OA.2, 3.OA.3, 3.OA.8
1 – Part-Whole Addition/Subtraction
2 – Comparison Addition/Subtraction

Intermediate

Common Core: 3.OA.3, 3.OA.8, 4.OA.2, 4.OA.3,
3 – Part-Whole Multiplication/Division
4 – Comparison Multiplication/Division

Advanced

Common Core: 4.NF.3.d, 4.NF.4.c, 5.NF.2, 5.NF.3, 5.NF.6, 5.NF.7.c
6 – Part-Whole Fractions
7 – Comparison Fractions

Challenge

Common Core: 2.OA.1, 3.OA.8, 4.OA.3
5 – Two Step (mixed operations)
 
 
 

All of these build towards support and modeling described in:
6.RP.3.b, 6.RP.3.c, 6.NS.1, 6.EE.6, 6.EE.7, 6.EE.8, 7.RP.3, 7.NS.3, 7.EE.3, 7.EE.4.a, 7.EE.4.b, 8.EE.8.c

Older students might enjoy and benefit from the game as it strongly supports Mathematical Practices 1, 2, 3, and 4.
