These part-part-whole diagrams can be stuck to the top of student’s desk, as a desk visual, until students are fluent recalling these facts. Students with memory or processing difficulties can benefit from having visuals as permanent prompts.

Progression
In the next chapter of activities students develop different partitions for the whole of 10. The sequence of activities in the Bonds of 10 chapter is similar to past chapters: moving from identify bonds, to developing fluency, calculating, solving missing number equations and creating word stories.
