Number • Sharing · Getting started
Three treasure boxes
Share 14 counters between three boxes, with at least one in each. Show three different ways and explain how you know each uses all 14.
Give it a go
Try ideas with the activity tools, draw your thinking, or explain it in words. There may be more than one useful response. This activity does not save or submit your work.
What this explores
Conservation and systematic sharing. Look for a child who moves counters between boxes while keeping the total fixed, rather than recounting from scratch every time. Ask how they know two arrangements really differ.
A starting nudge
Start with one in each box, then share the remaining counters. How could you change a distribution without changing the total?
Take it further
What changes if every box must contain a different number?
For teachers
Ask students to compare strategies and explain what makes their response valid. These difficulty bands are provisional, not verified curriculum or year-level alignments.
