Happy weekend everyone! Today was my youngest daughter's first day of indoor soccer. We have not done soccer for the last 5 years!! I forgot what it is like sitting on the sidelines with all the other parents :)
I wanted to share a math lesson that I started with my class on Friday and you may be able to use this month. If you have read some of my other posts you know that there is a focus in our area on inquiry based math lessons, getting students to talk to each other about their thinking, having students teach each other and working towards consensus to build understanding.
On Friday I introduced our Halloween craft. It is based on this picture and post I found on Pinterest.
I have made these with a class before. I use wooden picture frames from the dollar store, Halloween coloured paint and googly eyes galore. Since I have been teaching some of these kiddos for three years they have made a frame but will be making a second one and they are excited!
Here is what I told my students we need to figure out. How many packages of googly eyes do I need to buy?
I asked my students what do we need to know to figure this out. I recorded their questions. Then I answered the questions that I could.
|First question was mine the rest are the questions that they thought we needed to solve before they could answer mine.|
I brought in a sample frame from my daughter's room. (I made photocopies of the frame for them to work with but didn't pull those out yet!).
I brought in many different packages of googly eyes. We looked at each package and recorded the amounts.
Then they did not know how to move forward. Through some discussion they understood they needed to know how many googly eyes per person. They thought they would just guess by looking at the packages or saying 1 pack per person or 2 people split a pack (some were concerned with the cost and did not want to say too many!).
I told my class I did not just want to guess and end up back at the dollar store for more googly eyes. I wanted a really good idea. Finally a few students decided we could cover the frame with googly eyes but not glue them down to figure out how many we need.
I took out the photocopies, gave each group 1 package of googly eyes and sent them off to figure out how many googly eyes we need to cover the frame.
Since there were different sizes groups had different answers. Some groups could not cover their entire frame and had to do some estimation.
We put the googly eye covered frames under the document camera to present each group's solution.
|A few samples of student work. Displayed this under the document camera and saved on a shelf till Monday.|
We recorded the solutions and then looked for an average number. We had just been working on number lines last week so we made a number line and decided 200 would be in the middle of our numbers.
Next they needed to figure out how many googly eyes that would be in total if each person needed about 200. Again some kiddos were stumped but we got there - 4000.
|A portion of our recording chart - how many pieces in a pkg. who used them, how many we needed to cover a frame using that package.|
We had to call it a day there. On Monday we will be continuing with this problem. They will need to decide how many packages I should buy in order to have 4000 googly eyes. They will be having fun making decisions, arguing with other groups and reaching a consensus for me so that I can go shopping. I will be looking to see how the talk to each other about their thinking and how they work with large numbers. My advanced kiddos will need to come up with multiple solutions or use a variety of packages.
My students were totally engaged in this problems - they were motivated since this math problem is related to our class, it is real to them and they will be making a Halloween craft soon! Real-life problems and a craft, both big motivators for my class on a Friday so I am linking up this idea with the amazing Joanne at Head Over Heels for Teaching for her linky...
I hope you can use this idea too. Be sure and check out other motivating ideas at her blog!
