Understanding angles (age 8+)
PROCEDURALMultiply side lengths to find areas of rectangles and represent whole-number products as rectangular areas
Mastery Evidence
- Calculate the area of a 7 cm × 9 cm rectangle as 63 cm²
- Draw a rectangle with area 36 square units and label its side lengths
- Solve: A garden is 8 m by 5 m — what is its area?
Assessment Prompt
“If [child] needs to carpet a room that is 5 m by 4 m, can they work out how much carpet to buy — using multiplication rather than counting squares?”
Prerequisites1
- Area by TilinghardAges 8—9
Show full prerequisite tree
- Area by Tiling hard
Must see tiling→multiplication connection before computing area via side lengths
- Measuring length (age 7+) soft
Length measurement experience supports understanding area as a 2D measurement
- Measuring length (age 6+) hard
Using standard measurement tools extends measuring with non-standard units
- Measuring length and height (age 5+) hard
Measuring with iterated units extends Y1 beginning to measure length
- Comparing Lengths & Heights hard
Measuring length with units requires first being able to compare lengths directly
- Measurable Attributes of Objects hard
Comparing lengths/heights requires first identifying length as a measurable attribute
- Comparing Lengths & Heights hard
Ordering 3 objects by length and indirect comparison extends direct length comparison
- Measurable Attributes of Objects hard
Comparing lengths/heights requires first identifying length as a measurable attribute
- Capacity and volume hard
Using standard units for capacity extends from beginning to measure capacity
- Comparing Capacity hard
Measuring capacity with units requires first being able to compare capacities
- Measurable Attributes of Objects hard
Comparing capacity requires understanding capacity as a measurable attribute
- Measuring length and height (age 5+) hard
Using standard units for length extends from beginning to measure length
- Comparing Lengths & Heights hard
Measuring length with units requires first being able to compare lengths directly
- Measurable Attributes of Objects hard
Comparing lengths/heights requires first identifying length as a measurable attribute
- Measuring mass and weight (age 4+) hard
Measuring mass with units requires first being able to compare masses directly
- Measurable Attributes of Objects hard
Comparing mass/weight requires first identifying mass as a measurable attribute
