My students enjoy this every year! Sometimes I assign it as homework and sometimes I offer this as extra credit. Students are given math problems in Spanish and the answer equals a number that corresponds with a color. They are coloring the picture of a skeleton Day of the Dead dog.
I have used this with grades 7 to high school seniors. Makes the younger students think a bit and it's great review of number, math and colors in Spanish for the older students.
Great way to get in some learning and celebrating Dia de Los Muertos!
