Document Summary
Reading assignment: wright 64 -67, 82 85, 98 - 104. Part one: structuring numbers 1 to 10 (64-67) Use of 5 and 10 as reference points. 1+1; 2+2; 5+5: partitioning numbers 2 to 5: 2 into 1+1; 3 into 1+2 & 2+1; etc: partitioning numbers 6 to 10: 6 into 5+1, 4+2, 3+3, 2+4, and 1+5; etc: doubles to 20. Teaching combining and partitioning: subitizing attach numerosity to collection of objects immediacy. Develop familiarity with dice patterns encourage numerical thinking about visual observations: spatial patterns flashed on overhead projector involves entire class. Promotes discussion: finger patterns should be encouraged in early years supports development of more sophisticated strategies. Often used to assist basic mathematical functions (addition, subtraction, counting, etc. ) Use for solving multiplication and division: using double- or triple-counts. Helpful uses learning 1-5 patterns on hand learning 6-10 patterns on both hands. Using for addition in 1 to 5 range.
