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

Have these things available so your child can complete this task.

Ideal

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.

Decorative text.

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

Options for your child

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.

Follow-up questions to ask your child

  • 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?

Extension/additional activity

Encourage your child to create their own cards to use in this game.
