A few weeks ago, I posted a blog about following up worked examples by asking "What would happen to the answer if I changed the question slightly?" Here's another example of this from the blog.

#Mathschat #MTBoS #iTeachMaths #Maths

Initial question:

Find the mean, median, mode and range for the dataset:

12, 13, 14, 17, 17, 19, 20

Answers:
mean = 16, median = 17, mode = 17, range = 8

What would happen if I changed the question?
What would happen if we increased the last number by 1 (20 to 21)?
Which summary statistics would change? Why?
Which summary statistics would stay the same? Why?

4 million+ linear equations, one click each. Transum's updated eQuation Generator now shows the working line by line, has simple, medium and harder levels, and links students to a self-marking exercise.

A new exercise on the Properties of 2D Shapes requires students to simply move the sliders to describe each shape: number of sides and angles, pairs of parallel sides, lines of symmetry, rotational symmetry etc... 6 levels!

I often need graph paper with axes already drawn, ready to paste into BitPaper, PowerPoint or Word. This updated page is my go-to for quick, neatly presented results. You may find it useful too.

A classic logic puzzle has been given a Transum home:

I've called it "Only One Each". Place the tents so that each tree has one tent next to it and no two tents are next to each other.
