Over the next two weeks, our math class will finish the chapter 1 lessons of learning how to connect, Put Together, and subtract, Take Apart, problems. Students are addressing real-life problems and learning the difference between practicing addition and subtraction. We will then take our post-test.  

The vocabulary words associated with this chapter are:  

countback

count on

addition

subtraction

more

less

Ways to Support Your Child at Home:

There are many situations at home that you can use to model addition and subtraction. The kitchen is a great place to start! The maximum sum of objects for any activity in this chapter is 9. This aligns well with many cooking recipes. When preparing part of a meal, or baking goods, use the following strategies: • To model addition, separate the tomatoes, carrots, eggs, cups, or other food objects you are using for a recipe into two groups. Ask your student to count the number of objects in each group. Then ask, “How many are in each group? How many are there in all when I join the groups together?” • Show your student the number of objects you currently have to make a food item. Then tell your student that you need a certain number of these objects (9 or fewer) for the recipe. Ask, “How many more do I need?” • To model subtraction, show your student the number of objects (9 or fewer) you currently have. Then tell your student that you need a specific number of objects (fewer than the given group) for the recipe. Ask, “How many fewer do I need?” • Model other scenarios, making sure to use terms such as “take away,” “join,” and “difference.” By the end of this chapter, your student should feel confident with the learning targets and success criteria on the next page. Encourage your student to think of other opportunities related to cooking to use addition and subtraction contexts, such as buying items at a grocery store. Have a great time in the kitchen!
