Conversions

As we continue working with measurement here are a few trick I have been working on with the class. There should be a similar chart in their binders and I their notebooks.

With metric, I taught them "king Henry died drinking chocolate milk" to remember each of the prefixes in the chart. "Units" can be either grams, Liters, or meters. As we worked our way through various word problems, I encouraged each child to draw out the chart and then do one basic conversion across the chart...1km=10hm=100dm=1000m=1000dm=.... Below shows the work we did going from 4 km to _cm. Of course this is just one way. It takes a lot of time, but is accurate when converting.  This method is just moving decimals to the left or right. We drew another chart and discussed how this is really multiplying or dividing by 10s. All of metric is based on tens.


Yesterday we started customary measurement and all your darlings had a chance to show their artistic skills with feet, yards, and tomatoes. :) we drew these out along with a conversion chart to help with measuring length. This week we will be focussing in various customary measurements. Your child should be bringing home their notebooks to help with conversions, but I will also upload pictures of our notes, so they are here too.
Your child also has a math sheet with some difficult word problems related to measuring length, capacity, and weight. They only have to do one each night after they have been taught that particular topic. Yes, they are challenging, and yes, we will share strategies and go over each problem the following morning in class.
