    Elementary students LOVE critical thinking activities in math. These addition and subtraction brain teasers were made for 1st, 2nd, or 3rd grade students to use when working on addition and subtraction within 100 in the classroom. These can also be called logic puzzles! They are great math activities for students who need math enrichment throughout the year. You can also use them for math talks.

    By buying the bundle, you save 50% off the price of the individual units.

    There are 120 puzzles included that are perfect for every month of the year. These brain teasers help students practice finding unknowns in addition and subtraction equations with numbers 0-100.

    A digital version has now been added for use with Google Slides and Google Classroom. You can now use this resource for distance learning!

    An easy activity to slip into a math center or project whole group as a math number talk! There is both a color and black and white version included to best fit your needs. Answer keys are provided for self-checking or teacher convenience.

    When I use these in my classroom, I put them in a math center. I print them 4 to a page so they fit in the color task card boxes you can find at local stores. I have students solve each one and then provide them with the answer key for self-checking. It's easy to use and print-and-go. No prep required!

    Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
    Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.
    Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
    Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
    Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
