Product Description
This is a double set of task cards (24 cards per set) designed to support 5.NBT.B7, which focuses on decimal computation. These cards focus on handling tenths, many involving subtraction from a whole.

I created these to help students who consistently try to regroup and make errors as they cross over the decimal point. I would like for many of these problems to be obvious, and yet I have kids who are solving 3 - 0.7 and they're busy crossing out the 3 to regroup. The majority of the cards feature visual models so that kids can see what they are removing (or combining). There are cards included to review the model itself (what decimal is shown), and there are also some answers included as mixed numbers. Many questions have more than one correct answer, which forces the kids to think more carefully as they work through and evaluate each answer choice.

The second deck is a little harder. Problems that are tenths subtraction from a whole no longer have the visual model, but the model is included to practice more involved regrouping. All cards are focused on working with tenths, although a few inequality questions give answer choices in the hundredths.

This is a 16-page PDF file that includes 2 sets of task cards (4 cards per page), a recording sheet for each deck (1 page for each), and an answer key for each deck (1 page for each). They are designed to build on each other.

I started really using task cards last year with my class, and I typically print multiple sets of the cards and partner kids up. They work together as they complete the cards. I often will use the PDF print options to print the cards a little smaller than 4 per page.

I have found an increase in the use of math vocabulary, and kids seem to be more willing to take a risk by defending a solution when they've arrived at their answer with a friend. It also gives me a chance to work my way around the room and sit with pairs of kids to talk about what they're getting. These could also easily work as a math center.
