In this lesson, you will learn to use ratio notation to describe the composition of different groups.

In this lesson, you will learn to scale up from one group to ‘many’ groups and use multiplicative relationships to calculate unknown values in the ‘many’ groups.

In this lesson, you will learn how to represent ratios pictorially and use these representations to justify the equivalence of ratios.

In this lesson, you will identify multiplicative relationships between 'times tables' and use patterns to solve problems in direct proportion contexts.

In this lesson, you will compare the side lengths of triangles, one of which is an enlargement of the other, and calculate the ratios of the lengths of corresponding sides.

In this lesson, you will divide oblique line segments into specified ratios by dividing the segment’s horizontal and vertical displacements in the same ratio.

In this lesson, you will divide a quantity into a ratio of the form a : b and compare the relative sizes of the parts to each other and to the whole.

In this lesson, you will divide a quantity into a ratio of the form a : b : c and compare the relative sizes of the parts to each other and to the whole.
