Today, we’re going to dive into how you can use pattern block puzzles to build math skills.

## The Math

When it comes to foundational math skills, counting tends to take centerstage. Don’t get me wrong – early number concepts are important. However, this focus tends to overshadow other foundational math skills, such as understanding shapes and building spatial awareness. Let’s take a look at some of the early math skills you can find within the shapes category:

## How to Play

Pattern blocks are blocks made up of the following shapes and colors:

They are commonly found in preschool classrooms, typically in bins or buckets. Pattern block puzzles start with an outline, such as the giraffe examples below (taken from Young Mathematicians). You solve the puzzle by filling in the outline with a combination of pattern blocks.

You can find many pattern block puzzles online, but I like these by Young Mathematicians because they break their puzzle outlines into three levels: color puzzles, internal outline puzzles, and full outline puzzles.

**Color Puzzles** are a great starting place because children can use the colors to guide them in determining which block goes where. The **Internal Outline Puzzles **take away the color hints, but leave the individual block outlines. The **Full Outline Puzzles** are the ultimate challenge. They require children to think critically about what shapes can fit in each space without any guidance other than the outline itself.

## Connecting the Math

Don’t let the simplicity of pattern block puzzles deceive you – there is* a lot *of math going on behind the scenes.

Before we even get into shapes, pattern block puzzles are great for building **resilience **and **problem solving strategies**. Trial and error is the primary strategy children will use. As children try to fit different pieces together in a variety of ways, they develop **persistence **and the skill of learning from mistakes.

Children build **spatial reasoning skills** as they explore how they can physically rotate and flip shapes to fit them into specific spaces. In the giraffe example above, children have to use two triangles in different orientations to fill in the giraffe body. This develops the ability to think about shapes **flexibly **as children recognize that although the triangles may look different, they are both triangles.

Color block puzzles and internal outline puzzles focus children’s attention on the **attributes **of each shape. Children use the number of sides, the length of each side, and the angle of each corner to guide their trial and error process.

As children move on to the more challenging full outline puzzles, their trial and error process focuses on **composing **and **decomposing **shapes as they combine blocks to create new shapes. By taking apart and putting together shapes, children also build an understanding of **part-whole relationships** as they see that a whole shape, such as a hexagon, can be separated into multiple parts, such as 6 triangles or 2 trapezoids.

## Bring out the Math

First of all, embrace the struggle! Your child will most likely struggle with these puzzles at first – and that’s ok. Trial and error and learning from mistakes are skills in themselves. Start simple with the color puzzles, be patient, and provide consistent praise: *Great job placing the shape within the lines! I love how you tried to turn that shape to fit the space. *

Build your child’s understanding of **shape attributes** by asking general shape questions throughout:

- How many triangles/squares/hexagons did you use?
- Which shapes have 4 sides? What do you notice about the length of the sides?
- Which shapes have 4 corners? What do you notice about the size of the corners?
- What is the difference between a triangle and a square?

Support your child’s **problem solving process** by modeling and asking questions:

- Think out loud to model your thinking:
*To fill this spot, I need a shape that has three sides. Which block has three sides?* - Ask,
*How many sides are you looking for? Which shape has that many sides?* - Ask,
*Could you rotate or flip the shape to make it fit?*

Deepen your child’s **spatial awareness** by asking them to reflect on their own process:

- Ask,
*Can you build that shape a different way with other shapes?* - Ask,
*Why did you choose this shape?* - Ask,
*Why didn’t that block work? What will you try next?*

## Take Action

- If you don’t have a set of pattern blocks , get your hands on some!
- Buy a set – you can get them anywhere, but this set from Kohl’s is on sale!
- Print these and cut them to make your own “blocks” (taken from Jessica’s Corner of Cyberspace)
- Check out this online version. While physically working with the blocks is ideal, this free online tool is a great alternative to buying blocks.

- Choose 2-4 puzzles you want to start with and print them off – remember to start simple! Check out these from Young Mathematicians:
- Commit to playing pattern block puzzles with your child once this week. Add some accountability by scheduling it in!
