Lessons 6-9 focus on multiplying multi digit numbers by a single digit number. First, we learned about representing equations on a place value chart. Next, we learned about the partial product strategy. Today, we learned standard algorithm - the way we learned to multiply when we were in school! Students were presented with the place value chart and the partial product strategy first to understand what it actually means to multiply. After today, it is up to them to choose the strategy that works best for them.
