The diagram shows an L-shaped courtyard. Every corner is a right angle, and all side lengths are in meters.
Draw the split on the courtyard. Use separate paper for your equation.
Split the courtyard into two nonoverlapping rectangles. Write an addition equation using the two rectangle areas, then find the total area in square meters.
Is this a good fit?
A plain-language look at readiness, thinking, time, and the expected response.
Math readiness
Uses Middle Grade 3 math.
Thinking
The solver chooses and coordinates familiar methods.
Time & response
Light amount of written work · Construction response.
How to support: The learner may choose any valid two-rectangle partition and draw it directly on the plan.
Technical reference
Designed for Grade 3 · Uses Middle Grade 3 math · About 2–6 minutes
Grade 3 · Measurement and units · Area and perimeter
Precise MJD coordinates, factor scores, skill weights, calibration evidence, and curriculum crosswalks. This reference is available to everyone and is intentionally last.
Content level
Grade 3 progression · point 4
Challenge
The solver chooses and coordinates familiar methods.
Workload
A short response with only a few steps.
Learning focus
What a successful response demonstrates, with each skill’s share of the content rating.
The learner can find rectangle area by multiplying side lengths. This capability is distinct from mere exposure to or isolated use of arrays; multiplication.
Readiness
Skills the rating assumes are already available to the learner.
The learner can interpret a product as equal groups or a rectangular array. This capability is distinct from mere exposure to or isolated use of Grade 2 arrays.
The learner can solve one- and two-step addition/subtraction stories within 100. This capability is distinct from mere exposure to or isolated use of Grade 1 story structures.
External alignment
Approved evidence-backed locations that support discovery. They do not define the MathJewels rating.
