# Creating and Manipulating Linear and Quadratic Expressions - Key Stage 3

This  collection of resources supports the teaching of Creating amd Manipulating Linear and Quadratic Expressions.

Here are some of the favourite activities selected by the NRICH team.

• Perimeter Expressions Create some shapes by combining two or more rectangles. What can you say about the areas and perimeters of the shapes you can make?
• Always a Multiple? Think of a two digit number, reverse the digits, and add the numbers together. Something special happens...
• Special Numbers My two digit number is special because adding the sum of its digits to the product of its digits gives me my original number. What could my number be?
• Quadratic Patterns Surprising numerical patterns can be explained using algebra and diagrams...

These are just a few of the activities on Creating and Manipulating Linear and Quadratic Expressions that you can find on the NRICH curriculum pages.

The activities below, taken from the STEM Learning website, complement the NRICH activities above.
