In this practical task, students estimate how many multi-link blocks equal the length of two common classroom items. They then check their estimate with the blocks, then measure with a ruler.
In this practical task, students estimate, and then measure, the weight of two objects using a number of multi-link cubes, a balance scale and weights.
Pairs of students play a game with four dice, calculate the probability of winning the game, comment on how to get a more accurate estimate of the probability, and explain whether the game is fair based on their results.
