Cookie map finished, what to do with the leftover Smarties? (No need to worry about those little chocolate rosebuds. I ate them all last night after the kids went to bed.) I actually had it all planned out. No opportunity to teach goes to waste in this house. Can’t have fun, or just plain enjoy a treat without attaching some learning to it. So today’s big excitement was Smartie Math.
Here’s what we did:
- We figured out how to balance a scale, then measured out 100g of candy for each of us. Explained about setting the scale to zero, and how to read the scale, talked about imperial vs metric.
- We separated out the colors, and counted the number of Smarties in each color. Lots of excitement here. Comparing numbers, predicting results. Talked about spelling.
- We added up the numbers to get our personal totals. Discussed adding strategies, showed Jay how to add the ones, then the tens.
- Compared results. Tee had 90, Jay had 94, I had 92. Decided that our scale wasn’t that accurate, learned how to calculate the mean.
- Made bar graphs to display results. Tee got practice, and Jay learned how to make one.
- Compared graphs. Again, big excitement. I had more green! Look at how many pink I had! etc.
- Noticed that while there was a range of numbers, they tended to bunch around 10 or so. Tee predicted that there were approximately equal numbers of each color in each batch of Smarties. Because there were 8 colors, he thought that the number of Smarties in each color group would be 1/8 of the total number of Smarties. Talked about predictions, hypothesese, and fractions. Decided to leave percentages to another time.
- I gave them a math problem: If we had 90 Smarties in 100g, how many Smarties would we have in 1 kg? Talked about the prefix kilo, about the number of grams in a kilogram, the number of meters in a kilometer, and the different ways of solving the problem.
We showed great restraint, and only ate 5 Smarties each. Tee quite excited about making a bar graph to display the results using ALL of the smarties, hoping to prove his hypothesis correct.
To me, this little project is a good example of how much learning can take place in one interaction, and how multidisciplinary it can be. I didn’t have a plan other than making bar graphs, but the kids learned a lot of other things as well. They led the learning with their questions, and are extending it with their ideas.
