Patterns with shapes
Topic Notes
In this lesson, we will learn:
- How to identify patterns with shapes
- How to describe and draw sequences of figures (compound shapes)
- How to predict the next figure in a sequence with shapes and numbers
Notes:
- A pattern is something that repeats over and over again
- It could be a set of number, alphabetic letters, colors, objects, shapes, etc.
- To create a pattern with shapes, there must be a repeated order
- Ex. triangle, triangle, square, triangle, triangle, square, triangle …

- The order of shapes goes “triangle, triangle, square” and repeats
- Using the pattern, you can predict what shape will come next (for this example, the next shape in the pattern is a triangle)
- More complicated shape patterns use multiple shapes to build compound shapes
- Each new form of the shape can be called a figure in the pattern sequence
- A sentence description can be used to describe a pattern and help predict the next figure
- Ex. “add one more block to the right and bottom sides of the figure each time”

- Creating a table for the figure number and the number of shapes can help you see number patterns too!

- For this pattern, two more squares are added each time. You can predict that the 4th figure will have 7 squares (5+2=7)
