If I'm going to do a pattern activity I might as well do a number activity with the lego duplos too! I'll be making some of these templates for the lego duplo house party as well! Counting Coconuts: Rainbow Activities - Part I
What a great way to learn math! What kid doesn't love Legos? Again I would laminate these to be reusable, provide Legos to use as math manipulatives. Students could solve the problems and then self check using the Legos.
