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 ...

• TLF-IDA004597

In this first of two lessons, students investigate and play a First Nations Australian children’s instructive game of throwing skill called Kolap. They collect and represent data, and discuss their findings.

• TLF-IDA004284

This activity provides a way for children to show and tell what they know about numbers. It can be modified for different age groups and used every day with a different number.

• TLF-IDM024877

This sequence of four lessons focuses on counting large collections of objects and developing efficient counting strategies. Students explore the ambiguous nature of a 'handful' and investigate how different sized hands and different grabbing techniques will result in different quantities of macaroni. Each lesson is outlined ...

An abacus is a tool that helps people solve maths problems. Why might some people still use, and encourage the use of, an abacus when there are more contemporary tools like calculators?

• TLF-IDM012235

This is an interactive resource that represents numbers visually as groups of hundreds, tens and units. It can be used to count numbers by partitioning them based on place value, or to represent numbers by building them from grids of hundreds, tens and units. The numerals matching the visual representations can be visible ...

• TLF-IDM021824

This lesson explores counting large groups and building skip counting strategies. Students use their own strategies to work out how many birds are in a picture. They are then encouraged to consider efficient counting strategies and to recount the collection by grouping birds and using skip counting strategies. The lesson ...

• TLF-IDM008811

This is a 29-page guide for teachers. The module introduces addition and subtraction of whole numbers.

• TLF-IDA005643

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 ...

• TLF-IDA005649

As a team use the area model and mathematical thinking to find the answer to tricky calculations. Mathematical ideas and strategies this game supports: area model for multiplication; 1 x 2-digit multiplication; 2 x 2-digit multiplication; identifying factors; partial products; distributive property; place value partitioning ...
