This week, students will show their mastery of multiplication of two-digit numbers by one-digit numbers. We are doing this by allowing students to explore various representations for multiplication. This week, we are focusing on the area model for multiplication. Students will be able to build their own area models using base ten blocks by the end of the week. A sample area model is shown below:
This is going to be a busy week for our fourth grade mathematicians! On Monday, students will take a District Learning Assessment which will check-in to see their progress through the first nine weeks of school. On Tuesday, we will begin exploring the concept of multiplication. We will begin by looking at the strategies that students already know for multiplying a 2 digit number by a 1 digit number.
On Wednesday, students will practice using the partial products strategy for multiplication. This strategy breaks numbers apart by place value to make them easier for students to multiply. An example of this strategy is shown below.
We will continue practicing this strategy through the end of the week, applying it to problems which multiply a 2 digit number by a 2 digit number.
This week we will wrap up our unit on decimals. We will spend the first four days of the week doing our guided math rotation, where students will work in small groups to practice decimals in a variety of contexts.
After our guided math rotation is finished, students will show what they have learned by completing a test over decimals! The test will be administered on Friday, with a review sheet going home on Wednesday. Once the review sheet goes home, it will also be uploaded here for you to access.
