We can’t think of a better way to warm up for our 2021 Tumbleocity season than with a mathematical baking contest!

For a little inspiration: check out “Geometry Is as Easy as Pie” author Katie Coppens’ video showing her making an awesome pie recipe that you can try yourself (with parental permission of course):
