Construct a paper clock by partitioning a circle into halves and quarters, and tell time to the half hour or quarter hour. Foundations for Addition and Subtraction Within 20 Standard: Count up and down between 90 and 1, using ones, tens, and hundreds. Relate manipulative representations to the subtraction algorithm, and use addition to explain why the subtraction method works. Collect and record measurement data in a table; answer questions and summarize the data set. Use math drawings to partition a rectangle with square tiles, and relate to repeated addition. Relate doubles to even numbers, and write number sentences to express the sums.
