Inequalities - Using the signs correctly, listing integer results and inequalities on a number line
For KS3 or KS4 (particularly low ability).
"Crocodile eats the bigger number" using the signs correctly between two values, then between 2 sums, then with a little bit of simple algebra (with values of a, b and c given).
Listing the possible integer solutions of a simple inequality.
Representing inequalities on a number line, and writing inequalities down from a number line.
Quite a few answers to odd questions are done for them to help the students check their own approach as they go.

How Many Boxes Fit? (Relating to Enlargement and Area/Volume Scale Factors)
Short worksheet to prime students to think about how small boxes would physically fit inside a larger box, rather than simply work out the volume of each and divide to work out how many fit inside (which may not work if the boxes don't fit snugly).

Scatter Graphs
KS3 and KS4/GCSE activities on Scatter Diagrams/Scatter Graphs.
Includes
* a cheat sheet that I print on A3 in colour to put on the desks for them to refer to (can also double as a classroom display
* a quick sorting activity where students pair up types of correlation to pictures of graphs and pairs of variables that would match each graph
* a worksheet where students decide which scenario must go with each graph, and give reasons, and a prompt sheet with some suggested generic reasons for those who need it
* some exam questions that I have edited a little to include parts asking students to identify types of correlation and describe the relationships in context
