# Package 5-4: Origami cube and net exploration

This activity offers your child the opportunity to explore how a net requires each face to be connected to at least one other face.

Week 6 - Package 4 - Year 5 and 6 Mathematics - Origami cube and net exploration

## Things you need

### Back up

Watch the video from youcubed to see one way of playing with the number cards.

## Why is this activity important?

This activity offers your child the opportunity to develop their understanding of multiplication without time constraints.

## Before you start

• Make sure you have the required resources ready.

• This activity can be played individually, with a partner or with a group of people.

## What your child needs to know and do

This activity encourages your child to make connections between different representations of numbers and gain flexibility with multiplication.

## What to do next

How to play

• Play this game is like memory or concentration. Using the youcubed math cards, you are aiming to match cards with the same value shown through different representations.

• Print the youcubed math card handout and cut out the individual cards.

• Lay all the cards down on a table and then take turns to pick them up, looking for a match.

• For example 9 fours can be shown with an area model, a set of objects such as dominoes, and the number sentence (equation) as well as the product, 36.

• When players match the cards they should explain how they know that the different cards are equivalent in value.

### Activity too hard?

Encourage your child to watch the video again. They may like another opportunity to think about the mathematical ideas explored in the video.

Have a look at the cards on page 1 and discuss how the representations relate. Then use the first 3-5 pages of the math cards.

### Activity too easy?

Ask your child to think of other ways to show a representation of the number fact represented.

• How are you deciding that these cards go together?

• What does that card mean?

• Why are those two representations the same?

• How many dominoes can you see?

• How many are represented on each domino?

• What’s the total on that card?

• Can you explain your thinking a little more?
