Ratio

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

Groups

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

In the same ratio

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

Equivalent ratios

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

The rule of four

In this lesson, we 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.

Ratio and proportion in geometry I

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

Ratio and proportion in geometry II

In this lesson, we 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.

Dividing into a ratio I

In this lesson, we 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.
