Fractions, Decimals, Ratio and Percent

2 Apr

We’re in the process of looking at how fractions, decimals, ratio and percent connect. We started off with our interactive math journals to set the foundation for these concepts and create a place that would help students find answers or review processes –  we also decided to add in a section on relating these to our benchmark percentages.  During the week, we used an activity wherein students coloured a pattern or image on a 100s grid in order to help students visually see the relationships. It also allows students to see another creative connection between art and math.

They enjoyed the activity and it seemed to help them see the relationships. After this however, when we were working on some pattern block fractions tasks, we noticed that the students were struggling with the some of the key concepts.  We were thinking that one part of the problem is that we do often present students with items such as the perfect 100s grid when looking at fractions. Consequently, we started to use fraction talks, to look at different shapes and how to determine the fractions within that shape.

As a next step, we think we will revisit our grid by changing the size or how it has been segmented to see if students can show the changes in their learning. Not certain if we will do this through a fractions talk or have them complete it and record their thinking.  As well, we may adjust our ratio column to look at part to part ratios versus part to whole ratios. We are hoping the second piece will reflect a greater depth of knowledge.
