Can you beat the calculator? Players take it in turns to select numbers from the grid. You score the number you selected, your opponent automatically scores the sum of the remaining factors. Don't choose an abundant number! Think carefully and select wisely. Highest score wins. Try taking on the calculator as your opponent!

Two popular word games in one activity. Students use a program to extract letter frequencies from text and uses the data to analyse two of the most popular word games: Scrabble and Wordle. Students develop strategies for the second game and test them using the program: TIgram. 

Students use a range of visual representations to calculate the product of two digit numbers, including the distributive law, with a view to establishing efficient mental computation. After completing these exercises students compare these methods to traditional ‘long’ multiplication techniques.

The popular TV show "Letters and Numbers" screened on SBS between 2010 and 2012. The Numbers aspect of the show required contestants to use mental arithmetic to generate an equation equal a target number given 6 random numbers consisting of a mix of small and large numbers. Since the show aired, many teachers and their students have played this or similar games. This activity takes the basic game and extends it into a calculator program and an entire investigation sure to build students' arithmetic skills, estimation, problem solving and much more.

In this activity students plot a set of points that form the outline of a Christmas tree. Extension options include making the tree bushier, adding lights, blinking lights and more. 

Students plot points to form an image of their right hand and then use transformations: reflections, rotations and translations to draw their left hand or reposition both hands in a very visual activity.

Students are provided with a set of points which, when connected, produce the outline of a pumpkin and also a bat. Students plot the points and adjust the window settings to see the respective drawings.
