Week 5 - Package 1 - Year 1 and 2 Mathematics - Go fish: relationships

# Things you need

## Back up

• Create your own playing cards at home

# Why is this activity important?

Having strong knowledge of relationships between numbers is a critical part of developing number sense. It later enables students to work flexibly with numbers and operations.

# Before you start

It is important to vary your language as you play this game, asking about the same idea in different ways. For example

• 1 more than can also be expressed as “the number after”

• 1 less than can also be expressed as “the number before”

Give your child time to think and support them in working out unfamiliar number relationships. For example

• “Let’s see if we can work this out together...you have 4. One less than 4 is the same as the number before so we can count back to work out what that number is. We can start counting at any number, so let’s start at 4. (Show 4 fingers) Here’s 4. If I take 1 away, 1 less than 4, how many fingers are left?” (show 3 fingers and give thinking time to your child, letting them say 3. If needed, calmly repeat your thinking aloud).

# What to do next

Watch the Go fish: relationships video.

How to play:

• Each player gets 7 cards. The rest of the cards are place in a pile in the middle.

• Players try to make pairs that are 1 more, 1 less, 2 more, or 2 less.

• Once they can't make any more pairs, they can take turns to ask their opponent.

• If their opponent has a card of that number they must give it to the asking player.

• If they don't, they say 'Go Fish' and the player gets a card from the central pile of cards.

• Play continues until one player has no more cards left in their hand. They are the winner!
