## Bowling to Learn Subtraction: Great Guided Math and Center Activities

Bowling is a great way to teach children subtraction through ten.  Afterall, there are ten pins and when you throw, away they go.  Buy a real play bowling set from Target, Walmart or Kmart and roll away!   You can also make or downlowd bowling subtraction sheets.  And of course, there are virtual versions of bowling to practice subtraction!  I love the internet!

Be sure to have the children talk about what they rolled and what remains. This takes the conversation to the abstract level, especially if you record some of the thinking.  It might sound like this:  “So Maria, you knocked down 3 pins.  How many more pins do you need  to topple all ten?”  That type of question frames it as a 3 + ? = 10  Or, it might sound like this, ” Taylor, you had 10 and bowled away 5, how many are left?”  That type of question frames it as 10-5 =?

After you play this a great deal, you can set up these types of problems in the word problem center and students then have a context for solving these problems.  Remember that concrete, pictorial and then abstract scaffolds mathematical success!

Here are a few links to get you started!

## Great Number Counting Activities: Guided Math Explorations and Math Centers

Kindergarten Crayons has posted some excellent counting and cardinality activities.  These are very appropriate for kindergarten and early first grade.  I especially like the number maps and the surveys!

## Think Dot Activities: Great Math Center Activities

Think Dots is a great structure to provide for students to practice math concepts and skills.  Think Dots are designed with readiness levels, interests and learning styles in mind.  You can use these activities as on-going assessments.

Think Dot mats can be done with a variety of activities.  Each student rolls the die and then does the corresponding activity.  For example, if a student rolls a 1, then they do the activity designated in that square.  Here are a few math Think Dot ideas.

## Free Floor Sized Number Line

Marsha McGuire is the Best!  She has created a FREE Floor sized numberline!  What a brilliant idea!  It’s something the kids can actually use in a hands-on, feets-on way!  They can literally show you on the numberline by walking it or pointing to it!  It is a great FREE tool.  Did I mention it was FREE?!:)

*PS–Numberlines are a big part of the math CCSS.

## The Mathematician’s Chair- Becoming Public Mathematicians

Mathematician’s Chair – Public Speaking

Sitting in the Mathematician’s Chair during Share Time provides a stage to “show-off the genius within.”  It’s unbelievable what props can do.  Every mathematician’s Chair should be accompanied with the appropriate thinking and demonstrating tools -including magic markers (of course the kind that smell- everyone loves those no matter what grade) some chart paper, a pointer and a microphone for good measure.  I find that a microphone gives some special semblance of importance – I blame it on the talk show culture.  I have seen a microphone transform even the shyest of folk into people with something to say.
