Video kit shows children in K-12 classrooms using a variety of computation strategies and Unifix cubes to solve arithmetic problems in ways that make sense to them. The two videos feature classroom teachers using a teaching approach called Number Talks. The goal of this technique is to foster children's understanding of number concepts by engaging them not only in solving problems but also in discussing their strategies. Video one (26 mins) focuses on addition and subtraction algorithms with carrying and borrowing. It shows the difficulties children often have when asked to solve arithmetic problems. Video two (25 mins) analyzes the various methods children use to solve arithmetic problems. Ideas are given on classroom approaches to support children's mathematical thinking. Included in this video is a complete Number Talk presentation from beginning to end showing children's problem solving strategies and teacher interactions in an actual classroom situation. Contains guide and cards. From the series Math Time. | |
