## Daily Lego Maths: Day 21

What do you notice?
What do you wonder?

How would you describe this shape to someone who couldn’t see it?
Is there more yellow or red? How do you know?

What other mathematical questions could you explore?

## Daily Lego Maths: Day 20

Here is a picture made from Lego. Can you tell what it is?
How do you think it was designed?
What mathematical questions does this picture provoke for you?

Why not try making some similar lego art of your own?

## Daily Lego Maths: Day 19

Here are two shapes each made from 5 square blocks.

What other shapes could you make by joining 5 squares in this way?
How many are there altogether?
How can you be sure you found them all?

## Daily Lego Maths: Day 18

Here is a pattern made from red and yellow bricks.
Can you describe the pattern? What mathematical questions could you ask?

What fraction of the shape is yellow? How do you know?

## Daily Lego Maths: Day 17

A Triomino is a shape made from three squares joined together. There are two types of triomino, a straight line and an L shape.
You can make L triominoes out of lego by putting together a 4 by 2 and a 2 by 2 brick, with the same underneath but the other way round to keep it together.

Here is an L triomino and a shape made out of L triominoes. What do you notice?

The L triomino is a rep-tile, which means you can make larger copies of the tile using lots of small tiles. Here are some questions to explore:
By what scale factor has the L triomino above been enlarged?
How many tiles were needed?
Can you find a way to make other enlargements of the original?
Is it possible to make an enlargement of the original using any whole number scale factor?
Can you find any other Lego rep-tiles?

## Daily Lego Maths: Day 16

Here is a bus made from Lego. What mathematical questions could you explore?

How many wheels?
How many windows?
Might there be wheels and windows that you can’t see?

A bigger bus might have more wheels and windows. Can you draw or make some more Lego buses? How many windows would there be? How many wheels?

## Daily Lego Maths: Day 15

How many bricks?
How did you count them?

Is today’s shape similar to any previous Daily Lego Maths shapes?

## Daily Lego Maths: Day 14

Here is a Lego staircase. How many steps? How many bricks?

Make some staircases of your own. How many bricks do you need?

## Daily Lego Maths: Day 13

***Spoilers for Day 12 ahead***

Here are the seven possible tetrominoes you can make by joining together four squares edge to edge.

Is it possible to tile a 7 by 4 rectangle with these seven pieces?

## Daily Lego Maths: Day 12

Here are two shapes. What’s the same? What’s different?

How many different shapes can you make with 4 square bricks?
How will you know that you have found every possibility?

What if you use 5 bricks instead?
