During our math time this week we continued to break apart larger numbers into smaller partners. We used whiteboards and markers, counters, stair steppers, and activities from our math workbook to visualize the partners, switch partners, and doubles partners for the numbers 8, 9, and 10. Challenging your first grader to write and show each set of partners in a variety of ways has helped to increase number sense and flexibility with these numbers.
We also continued to use our knowledge of partners and patterns to practice addition (+0, +1, +2) and subtraction (-0, -1, -2) facts. This week in particular, we practiced adding and subtracting doubles partners (1+1, 2-1, 2+2, 4-2, 3+3, 6-3, etc.), and discovered that a number minus itself equals 0 (8-8 = 0). Next week, we will take our Unit 1 math assessment and also pretest for Unit 2.
