This sequence of four lessons explores the relationship between an informal unit of measure and what is being measured using the context of designing a game of 'Target Ball'. Students work in groups to collect data on how far their chose ball rolls, using a cut-out foot as an informal unit of measure. They represent and ...

This sequence of two lessons explores sorting numbers and place value. In the first lesson students identify the value of digits in a number and also build correct terminology to sort and describe 1-digit, 2-digit and 3-digit numbers. In the second lesson, students are challenged to use Venn diagrams to sort and describe ...

Challenge your understanding of place value in whole numbers up to 99. Receive a starting number, such as 86, and work towards turning it into a target number, such as 18, within 20 turns. Spin a random digit, choose its decimal place value and use the given operation (either addition or subtraction) on your starting number. ...

In this sequence of three tasks, students take handfuls of macaroni and investigate efficient counting strategies to check whether their handful contains 100 pieces. Students explore how organising a collection into equal groups makes counting quicker, easier, and more accurate. Different arrangements also support them ...

As a team, use your knowledge of different strategies to find the total number of Thundergoats as efficiently as possible (e.g. use combinations for ten). Mathematical ideas and strategies this game supports: noticing how items are organised can help you work out their total (subitising). There are many ways to add and ...

Make some music by building up rhythms for four instruments. Choose a starting point on a number line and build a counting rule. Count in lots between 2 and 10 until you reach 36. Add your number several times on the number line to make a pattern. For example, set up a sound pattern where a trumpet waits on the first note, ...
