The One with Individual Tangent Practice

I’m a bit more into individual practice, these days. A few years ago, I think I was more “all groupwork, all the time”, but I’m appreciating the fact that a decent culture of groupwork at our school helps support our kiddos when they’re working individually¬†while also allowing them to spend time on what they need.

We’re still working through how reference angles are related to tangent ratios (without really calling them that – most kiddos are sticking with opposite and adjacent sides). Also trying to balance procedural work (especially with ratios) and conceptual thinking. Someone made a decision with this curriculum to round some of the tangent ratios to numbers that made it easier to solve for unknown numbers. While this may take away from the actual ratios (which are a calculator button push away, anyway), it did give a lot of kiddos access who weren’t familiar with solving ratios. Lots of struggle today and I’m hoping kiddos got something out of it.2017-03-10 17.39.31-2What do you notice? What do you wonder?

Day 25: Individual Practice with Expressions

It’s getting to the end of our simplifying unit (which extends into other units, later on, hence the shortness). Some kiddos need more practice. Some have already seen this. We do individual practice, which means lots of little papers everywhere. I also miscalculate (many times) and make up to 4 times as many copies as needed. Lots of paper.

Big takeaway from this unit is that area and perimeter are a great way to encourage simplifying expressions in a realesque setting.
