## The Multiplier (2-digit by 2-digit numbers)

This unit uses The Multiplier, one of the digital learning objects that can be found in Te Pataka Matihiko, Our Digital Storehouse, to multiply 2-digit numbers by 2-digit numbers. It is designed for students working at Stage 7-Advanced Multiplicative of the Number Framework and is the third in a series of four units that focus on using the Multiplier as an aid to learning multiplication.

Resource

## The Multiplier (origin of the algorithm)

This unit uses The Multiplier, one of the digital learning objects that can be found in Te Pataka Matihiko, Our Digital Storehouse, to multiply 2-digit numbers by 2-digit numbers. It is designed for students working at Stage 7-Advanced Multiplicative of the Number Framework and is the fourth in a series of four units that focus on using the Multiplier as an aid to learning multiplication. In this unit, The Multiplier is used as a tool to outline the origins of the standard algorithm for multiplication.

## The divider (mixed number quotients)

This unit uses two of the series of four Divider learning objects to support the students division of whole numbers where the quotient is a mixed number (whole number and fraction). The Divider encourages the students to split a division problem into parts based on known division or multiplication facts. The divider is based on a rectangular representation of division where one of the side lengths is unknown.

Resource

## Multiplication and Division Pick n Mix 1

In this unit we look at a range of strategies for solving multiplication and division problems with whole numbers with a view to students anticipating from the structure of a problem which strategies might be best suited. This unit builds on the ideas presented in the Multiplication Smorgasbord session in Book 6: Teaching Multiplication and Divsion.
