7 resourcesMidpoints and Ratios
The midpoint of two points, an end from the midpoint, and two unknowns; then points on a line segment in a ratio: find the ratio (AB : BC or AB : AC), the point between, an end, and two unknowns. Seven levels, timed, click to…
⚙️ WorksheetStraight Line Graphs: Spot the Mistake
A student’s working with a mistake a real student would make (or, about 1 in 8 times, no mistake at all): tap the line you think is wrong, or No mistake, then reveal it, the corrected working and why. One level for each part of…
