Such a great idea! Mom to 2 Posh Lil Divas: What Time Is It? - A Telling Time Review Game (Okay, I'm thinking something like this could be adapted to teach time in Spanish. Have the clocks or the time in numerals on one half of the egg and the time en español (written out in words, of course) on the other half).
My students love these number puzzles. They are a great way to practice different strategies for adding and subtracting two-digit and three-digit numbers. They help students play with decomposing numbers to build addition and subtraction math strategies for second grade.
