This week in math we are working with the part-part-whole model and noticing similarities between subtraction and addition equations. For instance, we notice that knowing the fact 8+2=10 can help us solve 10-2=8. As students become more fluent and confident in their facts, these relationships should become more clear and students can use them as a tool in their every day problem solving. We continue to work mostly on facts within 10, but in the next couple of weeks will be moving to higher facts up to 20.
We also continue to work through a variety of story problems together, with increasing rigor. Students are learning that not all story problems are a basic add or subtract problem. They need to think carefully about what the question is asking and make a plan to solve it using addition, subtraction, or sometimes both!
This link is a great resource for practicing math facts up to 20. We will be using it some at school. Feel free to practice at home, too! http://www.aplusmath.com/flashcards/
