This morning, Teddy worked on understanding the hundreds chart with a plus 1, minus 1, plus 10, minus 10 puzzle activity. Then, he completed fast fact checks on adding 1 through 9 and subtracting 1, 2, or 3. Teddy used different highlighters to mark the facts with the addition strategies that have been learned such as friends of 10, doubles, and plus 9. Finally, Teddy answered cumulative review questions on understanding addition.
