If you're always searching for new and challenging activities for your math centers, you and your students will love this set of 24 math riddle task cards for two digit addition with three addends.

This resource is also included in Three Addends Two Digit Numbers Riddle Activities Bundle. You'll get twice as many riddles plus components for digital use in the bundle!

Here's how math riddle task cards work!

Choosing from four numbers on each card, your students will use their addition skills to determine the secret number by eliminating three of the options. With each card they complete, your students will solve three addition number models with three addends – that’s 72 in all!

students moving to stations around the classroom to solve the riddles.

♦ Use as enrichment to keep your fast finishers learning!

♦ Paraprofessionals and parent helpers love to use these cards, since they can use as few or as many as time allows, still giving students a sense of completion.
