*Hello all! I am excited to be guest posting here on Corkboard Connections. Today I’ll be sharing an easy, low prep way of reviewing multiple math concepts with grocery flyers.*

If your mailbox looks anything like mine, it is overflowing with junk mail. One of the biggest culprits is grocery flyers. I receive weekly flyers from four different stores, and they really pile up in the recycling bin. I was staring at the pile one day, and an idea struck me. Real world problem solving was staring right back at me!

On my way to the classroom the next day, I grabbed a handful of flyers to give my idea a try. When small group math time came, I fired out a few questions to my students.

- Have you seen these before?
- What might you use them for?
- What do you think we are going to do with them?

**Getting Started with Grocery Flyer Math**

My plan was to take these flyers and do a complete review of our math concepts from the year.

We started with each student choosing an item, cutting it out, then gluing it to an index card. On the index card we recorded the price in standard, word, and expanded form as well as drew a base ten model.

The next step was to take these items and compare them. We ordered them from least to greatest then placed them on a giant number line. We also converted our decimals into fractions, and that was just out first day!

**More Math Concepts to Explore**

I was so impressed with how engaged my students were by these grocery flyers, so I went home after that first day and thought about what else we could do.This is what I came up with:

**Rounding**—round the price of each item to find an estimate of the total bill.**Adding and Subtracting Decimals**—this is even more fun when you find a flyer that has coupons, because it is more authentic practice!**Multiplying Decimals**—for when you need more than one of an item or for adding tax to a purchase.**Multi-Step Problem Solving**—students create their own problems based on items and coupons then trade with a partner.**Planning**—find a recipe and plan a meal. Then figure out the cost of the items.**Graphing and Data**—use the prices or types of items as data to create tables, plots, or graphs.**Measurement problem solving**—decide what unit of measurement would be used for each item. Make a list of how much of each unit you want to buy.**Geometry**—identify any 3D shapes you can find.

Great post! :)

ReplyDeleteLove it! I've done this before, but not like this and it was years ago! Thanks for the reminder and ideas!

ReplyDeleteAmazing post! I have never thought to do this before which is crazy! I would love to do this and include some ideas about personal finance and shopping around. So many possibilities!

This is greatI! With summer coming, I'll be sure to do this with my kids over break.

ReplyDeleteIt was good idea . You need to prepare organizer like them

ReplyDeleteI teach 3-6 math and I was looking for ways to make a workstation for all four grades. This will be fantastic.

ReplyDeleteI just work with preschool but I've learned I'm not doing enough math. So I have been looking for different ideas to do more math in centers this will be great. The only one I can do is putting them in order but at least there working with numbers, but then I could do graphing on how many time they can find items in a month of collections of flyers.

ReplyDeleteLove these ideas. I am now in the unit of operations with multi-digit decimals. So these will come in handy. Thanks
