The **number decomposition chart **can be used to teach multiple ways a number can be decomposed. Write the whole number (e.g. 10) in the box on top and make the possible decompositions (e.g. 4 and 6) in pairs on both sides of the line below. You can also fill it out partially and let students complete the gaps.

The **number bond chart** can be used to teach number bonds. Write the whole number (e.g. 8) in the big circle on top and write a pair of matching parts (e.g. 3 and 5) in the smaller circles below. You can also leave one or two circles empty and let the students complete the chart.
