Day 22: Number Pattern Christmas Lights

Thanks to the excellent crew on the department's social network Maang (specifically the Maths group Axiom) once again for a brilliant idea. The original was Christmas trees that lit up. My version is strings of Christmas lights.

Each string represents a number pattern and each bulb is a term in the pattern. Type in the missing terms in the blank (white) bulbs. When you finish the last term, the whole string lights up! It's pretty funky!


The first sheet is addition and subtraction, staying in the positive numbers. The second is addition and subtraction including negatives. And the third is multiplication and division patterns.

Here's an idea of what they look like when complete.

Have fun! I hope you're all enjoying the last week of term. I know I am.
