## Subtraction Strategies

Great ideas for teaching subtraction strategies in 2nd and 3rd grade. **The actual structure is good for all grades.** Notice how she frames the problems on the board, this is a great way to jumpstart mathematical conversations about strategies.

## Math Fact Cards

Hello my friends,

Here is a great resource for math fact flash cards. I love that they are sorted by fact type. Be sure to set up a math fluency workstation that is leveled. Meaning that, some students would be practicing make ten facts while others would be practicing doubles. Super important that students practice in their zone of proximal development.

## More about Bowling for Subtraction Facts!

Bowling is a great guided math activity as well as a great game to play during workstations. Students stay engaged and they actually do learn all their combinations through ten because of the repetition element! Here are some links:

Link 1 Must see! Who knew that plastic cups and a tennis ball could teach the facts!

LInk 2

Link 4

Link 5

Link 6 (Facts through 5)

## Thinking More about Addition and Subtraction

Here are some great examples! What type of communication do you send home to your parents about the new common core? Has your school made a parent handbook to explain the new algorithms and strategies?

## Ways to think about subtraction!

Subtraction is much more difficult for children than addition. We don’t tend to teach enough subtraction strategies and have students play around with them in small guided math groups and math centers. Here are some ideas to add to your thinking about teaching subtraction.

Resource 2 (Be sure to scroll down to the illustrated examples!)

Where are your students along this learning continuum? What do you need to teach next?

## Interactive Individual Subtraction Books!

Interactive Individual Lapbooks are great ways for students to engage in a variety of activities around a specific concept. They do these alot in homeschooling, but they are great for public school children as well. It is a teaching structure for interacting with a concept. **On this site,** they have a lot of the blackline masters that would go in a Subtraction Lapbook!

## Subtraction Ideas

Here are 5 great subtraction ideas.

Idea 1 (it’s kinesthetic and visual!)

Idea 2 (a great way to illustrate subtraction in story problems)

Idea 3 & downloads (numberlines are super important! but remember they are abstract! do lots of concrete and visual first)

Idea 4 (I love this anchor poster)

Idea 5 (Scroll down to the vegetable subtraction. I love this too! Hands-on, interactive, visual. Just great!)
