Festive mental math coloring pages. With 15 problems on each page, differentiated into an easy, medium and challenging page. Answer pages are included.

Calculators shouldn't be used, but multiplication charts might be allowed. The use of scratch paper should definitely be encouraged (why are they always so reluctant to use it?) Kids could also work in pairs for additional support, or they could compare their answers with a classmate who is working on the same difficulty rating and make any necessary changes before coloring the decorative baubles.
