APRIL MATH MYSTERY: THE CASE OF THE APRIL ALIEN AMBUSH
(2ND GRADE EDITION)
Get your students engaged with a high-stakes investigation! "The Case of the April Alien Ambush" is an exciting math mystery where students solve clues to identify the imposter gnome agent in the G.I.B. who helped the aliens steal the Earth's color. This packet is a targeted review of spring 2nd Grade Common Core standards, making it the perfect engaging math center or whole-class review.
