4/6/2018 0 Comments Organizing into Groups of TensMathematicians compared A & B today, noticing that A was "everywhere" and B was "in a row" and "sorted." They also realized that in A, circles might be counted inaccurately because some might be counted again and some might be skipped. Students saw that in B, they could count by ones or by tens because the circles were grouped by tens. This is similar to E with using the blocks of ten. Again, all strategies were honored as we discussed how each strategy matched the story. Students were also given the opportunity to go back and try a different strategy.

4/6/2018 0 Comments Comparing StrategiesAs students are confronted with larger sums, they are finding that some strategies are more efficient and accurate than others. When we compare these different strategies, we still honor all the ways in which mathematicians worked out this problem and highlight how they all match the story. At the same time, we offer up other strategies that students use in the classroom and encourage students to try new strategies. Many mathematicians are using the #3 strategy, which allows students to see every pencil and count by ones. Some students are using the #2 strategy with tens and ones. A few students are using a counting strategy with a number line. As a class, we notice how each strategy matches the story and then we count each one. Students are noticing that one strategy might be more efficient and accurate than another strategy by the end of the summary. Then, mathematician have the option to go test out a different strategy.
