In Math this week we investigated addition and subtraction facts to 11. We explored different strategies for adding and subracting these numbers. The children recorded their answers on paper and had to explain their number sentences and the reasoning behind their stories. Most children understood the concept of doubles and discovered that doubles were also even numbers! We worked with the number chart and examined patterns. We reviewed the concept of counting by 2's and 10's. The children learned the meaning of capacity and weight.
