Students write the simplest algebraic expressions for the lengths and area of parts of a composite shape, then solve these expressions using substitution. They then solve an equation that relates an algebraic expression to a given side length.
The start of spatial matchstick patterns are shown and described in tables. Students complete the tables and show the rules in either words or equations.
Students interpret a graph of taxi company charges to show which company is cheaper and complete a rule for each company's charges. They also identify the distance at which each company charges the same amount.
Students study two graphs on some rocks and lake features of Saharan North Africa and answer a mix of questions to show this ability to interpret these graphs.
Students draw in the next two shapes in a spatial pattern, complete a table and rules about the pattern, then calculate the number of triangles in the 8th shape.
