Activity set-up
Activity set-up
Organise the students into groups of 4.
Provide students with a numberline or have students draw one.
Provide each group of students with a pack of cards, using Ace-9 to represent 1-9 (Ace to represent 1).
Setup a throw line 3m from a wall.
How to play
How to play
Players arrange playing cards into place value parts aiming to make a number closest to 1000.
Each player draws a card from the deck.
They throw and catch the ball at the wall the number of times represented on the card and decide if the number will represent ones, tens or hundreds. For example, if a 5 is drawn it can represent 5 ones, 5 tens or 5 hundreds.
The players take a second card from the deck, again throwing the ball at the wall and nominating if the number represents hundreds, tens or ones and adds the number to their first card.
Have the students record their total on an empty number line.
Continue the activity until each student has drawn 4 cards.
The player with the closest total to 1,000 wins.
Variations
Variations
Players start at 1000 and subtract the numbers, with the player closest to zero declared the winner.
Play with decimal numbers.
Players draw three cards from the pile and make the highest three-digit number possible. This becomes their starting number and they continue to play as in the above variation.
