Dogs have wings. Dogs have one eye. Dogs have zero legs. Dogs eat water bottles. Dogs eat number lines. Dogs eat hot dogs. Dogs eat dogs. Dogs have a red nose. Dogs have no tail. Dogs can fly. Dogs can eat anything." Just because it's on the internet, doesn't mean that it's true. We trust published books or peer-edited journals that have been checked for facts. 12/18/2018 0 Comments Comparing Large QuantitiesThere are two sisters. One is 65 cubes tall. The other is 53 cubes tall. How much shorter is one sister than the other?
Students needed to compare these two measurements: 65 cubes and 53 cubes. Most students set off, using cubes like the story suggested to compare the measurements. Other tools students suggested included; hundreds chart, number line, tiles, pencil and paper. Students are working on: 1. Using tools to match the story. Today, most students worked on using cubes with partners to match the 65 and 53. 2. Attending to the question. What is it asking us to do? Add all the cubes together? Say which one is shortest? It's asking us to compare. 3. Show their thinking on paper. How can I show that I saw 12 less cubes cubes? How do I show that I counted on? 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65. 12/14/2018 0 Comments Using the Number LineMathematicians have been counting on or comparing quantities and I have been showing them how the number line can be one way to record this thinking. For example, when asked how many more seashells Abdi had than Xavier, students may use their fingers to count on. "5, 6, 7, 8, 9, 10. Five more!" One way to show this thinking is with a number line.
