This activity allows students to explore how numbers are composed, by having them look at different ways of grouping them.

Can you explain why every year must contain at least one Friday the thirteenth?

This task helps students build number sense as they practice calculating.

This is a really nice task as it is open to everyone, can be solved in different ways and can also extend to work in combinatorics – a nice way of organizing counting.

Leo the Rabbit has become a Youcubed favorite.

Jo has used this task with a lot of success on the first days of school with very hesitant students. Soon after setting the challenge the board area becomes full of students putting up their solutions, then returning to their seat to look for more.

The activity encourages students and teachers to engage in visual, creative thinking. We have coupled Mark’s activity with asking students to reason and be convincing, two important mathematical practices.

In this class activity, students find the missing number to complete a number sentence while also seeing different representations made by other students.

This task reminds us of Four 4’s because students are practicing number combinations to get specific results.

Write the numbers 1 to 6 in a horizontal row. You (Player A) will play the Big Bad Wolf who is
Player B.

The game provides a great way to practice and build fluency in single digit multiplication.

This is a really worthwhile mathematical investigation that students may explore together.
