Describe and compare measurable attributes such as length, weight, and capacity.
What this standard means
- An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a "one-degree angle," and can be used to measure angles.
- An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
- Apply recognize angles as geometric shapes that are formed wherever two ray… with models and explanation
- Names measurable attributes

How to use the 20 practice sets
| Sets | When to use | | --- | --- | | 1–5 | Intro — explore together, short written items | | 6–10 | Core skills — diagrams and written practice | | 11–15 | Mixed review — explain thinking | | 16–20 | Stretch — word problems and mastery tasks |
Pacing: 10–15 minutes per session.
How to practice
1. Sort objects by one attribute at a time 2. Use comparison words: longer, heavier, holds more 3. Draw and label comparisons

Common mistakes
- Comparing unrelated attributes
- Using size when weight is asked
Review and practice tests
1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for 4.MD.C.5.
- [ ] Names measurable attributes
