My math lessons focus on student engagement and participation. I focus on developing conceptual understanding using manipulatives, specific language and activities. My lesson plans also include differientiated tasks that cater to the varying levels in the classroom.
Goals of this lesson:
1) To solve in-context problems involving addition and subtraction of decimals concretely, pictorially and symbolically
2) To create meaningful procedures with a detailed explanation of how to add/subtract any numbers involving decimals
If this is the first time students are learning about adding and subtracting decimals, you may do several lessons that are similar to this one until the students discover the patterns and procedures. If your students have already been taught this concept or rule, this approach will help bring more meaning and understanding to the procedures.
