Can you guess the code using the digits zero to nine?

I am a four-digit number.

My digits add to 11

I have 2 even numbers and 2 odd numbers

My largest digit is 5

Is there more than one answer?

Can you make up some questions for a different code?

Teachers should comprehend what students need to understand before and after this task. As part of the community other educators can make suggestions to similar tasks, pre-tasks and tasks that will scaffold students' understanding once they have developed this concept. For example, you may choose to use two-digit numbers with younger students.

Especially, in the early years, mathematical tasks need to be hands on, often designed to develop understanding of the same concept. Effective teachers often repeat an activity in a similar way with different materials.

As we share and contribute other ideas exploring mathematical concepts, these tasks can be used to model the specialised language teachers use to support numeracy with young children. This community can support the sharing of these ideas through conversations, sharing of ideas, resources, photos and descriptions of numeracy tasks.
