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. Ask students to work on this task in groups, and to display their results on posters. Often we name students' different approaches and strategies.

Students will be involved in an activity in which they decompose the number ten in various ways and then create representations to show all the different ways you can decompose the number ten. Students will also create equations to show their combinations to ten.
