Students are hard at work on our Unit 3 in math - Understanding Area! This unit focuses on real life application of measuring and calculating area and finding area for complex shapes. Students will develop an understanding of using square units to measure area. They will also learn about area as the amount of surface, and count unit squares need to cover a surface to determine areas of figures. Connecting area to multiplication is an important concept. Students will decompose rectangles and recognize that complex shapes can be decomposed into smaller shapes to calculate area. We will revisit the concept of perimeter and solve problems involving both area and perimeter of rectangles and discover ways to make rectangles of the same area or same perimeter. We will also continue reinforcing money concepts by solving word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ signs appropriately. Students will link multiplication by 5s to nickels and 10s to dimes. They will also solve area and perimeter problems with unknown side lengths. This unit will be completed before the break. There is much new learning and connections made in this unit! We will continue to reinforce newly introduced concepts throughout the year. Families can expect to receive an end of unit 3 Parent Communication letter when students return to school after the new year.

Dear Grade 3 Families,
This year, beginning in December, students will be assessed each month on a differentiated set of multiplication and division facts. Based on those results, and the particular problems students made mistakes on, students will be placed at certain levels. Students will be able to build fact fluency by focusing on the facts that are challenging to them and work their way toward end of year goals for 0–10 facts. The steps are broken down like this: Level O (2’s, 5’s, 10’s) Level P (2’s, 5’s, 10’s, 4’s) (if you know your 2’s, 4’s are doubling 2’s) Level Q (2’s, 5’s, 10’s, 4’s, 8’s) (if you know your 4’s, 8’s are doubling 4’s) Level R (2’s, 5’s, 10’s, 4’s, 8’s, 1’s, 0’s) (1’s and 0’s were placed here as an easy in between step) Level S (2’s, 5’s, 10’s, 4’s, 8’s, 1’s, 0’s, 9’s) Level T (2’s, 5’s, 10’s, 4’s, 8’s, 1’s, 0’s, 9’s, 6’s) Level U (all 0-10 facts) [Goal] Level V (11’s, 12’s) (for students who have exceeded the Grade 3 end of year goal) The goal for every level is to answer 35 or more questions correctly in 2 minutes for multiplication and 3 minutes for division. Level U is the end of the year goal for 3rd grade. Students should be practicing facts daily, especially if they have not yet made goal. Thank you for helping your child practice at home!
