Order numbers to at least 1000 on a number line
Number Line Four in a Row
Timeframe: 10-15 minutes
Audience: Partners
Materials: Blank number line printed onto A3 strips, two different coloured pencils/textas, 10-sided dice
Summary: In pairs, students take turns to roll two 10-sided dice and make a 2-digit number. Using their coloured pencil, they must mark whereabouts on the blank number line they think that number would go. Students take turns to do this, and are aiming to make four in a row along the number line in their colour. Meanwhile, their partner is trying to stop them so they might play strategically by making and recording a number that breaks up their sequence of numbers along the line. This task can be extended by using more dice.
Guiding questions: Why have you placed this number at this point on the number line? Point to a spot on the number line and ask, What number do you think goes here? How do you know? What are some numbers that you could roll to get another number in a row?

Summary:Â Players have one gameboard between two players. The deck of cards are facing down. Player one turns a card and then recalls the number before and after. If one of these numbers is on the game board, they put their counter on it. If player two has a counter on this number already, the say "Get outta my house!" and replace their opponents counter with their own. It is now player two's turn. The winner is the person with the most counters on the game board at the end of the game. This can be a set time or when all cards have been turned.
Guiding questions: What number are you trying to make? Explain to me how you got __? “What if you use multiplication (or subtraction) etc.? What would you do differently the next time you played?
