October-November+07

10/1/07: Begin Counting Collections. See "Counting Collections" article from the March 2007 edition of __Teaching Children Mathematics__. Set up heterogeneous partners that can work well together (one may be somewhat stronger than the other but don't pair the strongest with those who struggle the most). Each pair decides what they would like to count first. Materials available: post-its, trays to store unfinished collections on, worksheet (attached here ), labels to stick on completed collections, baskets to organize counted and uncounted materials. End the session with sharing of methods. 10/2/07: More Counting Collections. Begin with story problem as a whole class, ask them to visualize, determine the operation, solve, double-check, and write equation. End with sharing. 10/3/07: Begin with lesson similar to that of 10/23/06, introducing making groups of ten. As students count collections, tell them they need to practice putting things in groups of ten. No one should count more than 100 of something; many should be in the 20s, 30s, or 40s. Keep talking to students about groups of tens and extras and how we write numbers. End with making a class chart of how to count accurately (organize what you are counting, sort what you are counting, double-check, count by tens, fives, or twos, put things in groups, etc.) 10/4/07: same as yesterday, beginning with work on groups of 10, then send children off to count collections in pairs. 1/3 of class works on combinations of 8 using links with a teacher. 10/9/07: Choices: Double Compare, Snap it!; Counting Collections 10/10/07: Begin by teaching Counters in a Cup. 1/3 of class works on combinations of 8 with a teacher using links. The others choose between Counters in a Cup; Double Compare; and Snap It! End with small teacher-led groups counting a collection and putting it in groups of 10. 10/11/07: Begin by teaching Roll and Record. Some children record their equation, others just the total. (Teach in 2 groups). 1/3 of class works on combinations of 8 with a teacher using links. The others choose between Roll and Record, Counters in a Cup, Double Compare, and Snap It! 10/15/07: Begin story problems. practice visualizing, re-telling, determining the operation; end with sharing strategies. 10/16/07: Begin with whole-class story problem on rug. Choices: Roll and Record, Snap It!, Counters in a Cup, story problems. 10/17/07: In half groups: solve 2 story problems, then play Counters in a Cup. 10/22/07: In half groups, solve 2 story problems, then play Counters in a Cup or Snap it! 10/24/07: assessment of unit 1 10/25/07: Snap it/ Counters in a Cup, then story problems 10/26/07: Decomposing 8 problem 10/29/07: 11/19/07: pumpkin math story problems 11/20/07: begin with looking at poster of combos. of numbers from cube train work last week; discuss observations; more story problems work
