Product Description
Included in this download are two sets of task cards (52 cards in total) to practice place value relationships, computation with missing numerals, problem solving, addition and subtraction within 1000, higher-order thinking skills, and explaining one’s mathematical reasoning. I have used problems such as these with 2nd through 4th grade, though I could certainly see certain 5th graders benefitting from them, as well. These task cards will help support CCSS Standards 2.NBT.7, 2.NBT.9, 3.NBT.2, and 4.NBT.4.

Set One is comprised of 32 cards that feature 3-digit addition and subtraction with missing numerals/digits. Not missing numbers, but
digits. As a result, students are required to utilize their mathematical reasoning – not just computation – in order to find the correct answer. Students are also asked to articulate their thinking to a partner and/or in their written answers.

Set Two is called “Make It Work,” and it is pretty challenging in terms of the reasoning that students are asked to use. Every card has a set of 4 or 6 numerals. Students are asked to arrange those numerals in order to find the largest sum or smallest different of two 2- or 3- digit numbers.Again, students are required to explain their reasoning. This is a push for many kids. Often, kids will try to use computation to find
their correct combination of numbers. My goal with these cards is to get kids thinking about HOW to place the digits – do they notice any patterns? What is different about the 2-digit problems versus the 3-digit? Or, the addition versus the subtraction? Heady stuff!!

I’ve also included answer keys for the cards, as well as recording sheets. I hope that the recording sheets give your kids enough room to show their work. I’m easily frustrated when recording sheets only provide enough space for answers, but not for work. Instead of having pre-numbered answer sheets, I use recording sheets where kids write the number and color of the card for each box. We use less paper that way…if kids don’t get to every single card, I’m not left with piles of staples recording sheets with partially blank pages.

Thanks for checking it out!
