These task cards give kids the chance to practice place value knowledge and relationships, comparing numbers, addition and subtraction with the standard algorithm within 1,000,000, higher-order thinking, and explaining their mathematical thinking. Included in this download are two sets of task cards that emphasize comparing numbers and ask student to explain and show HOW MUCH greater or less than the numbers are to one another. I’ve also included answer keys, and recording sheets that provide plenty of space for kids to show their work. There is a page with four boxes, as well as a page with six. Use whichever is most helpful. These task card support CCSS 4.NBT.2 and 4.NBT.4. They are a perfect fit for 3rd and 4th grade, and might be appropriate for some 2nd graders or 5th graders.
Set One (20 cards in all) uses numbers that are 3-5 digits. Set Two (20 cards in all) uses numbers that are 4-6 digits. The directions on the card instruct students to say the comparison out loud. For example, “16,397 is greater than 10,061.” The second part of the direction states that students must explain how much greater or less than the numbers are in relation to one another. Because the 4th grade standards specify the standard algorithm for addition and subtraction, the directions do state that students should use it to. However, the directions also state that student should use a different strategy or algorithm to show that their answer is correct. Asking for that extra level of thinking gives these problems the extra ‘push’ I think is important to incorporate with task cards. Simply writing a comparing expression with a greater than or less than symbol doesn’t give kids the opportunity to articulate what they know. I also think it’s very important for kids to get into the habit of checking their work. Hooray for higher-order thinking and academic responsibility!
