Math goals for January

I hope you are enjoying the winter break. I’ve noticed some students have been getting on ixl and practicing their skills. We will continue to focus on multiplication and division facts.

# 3.OA.C Multiply and divide within 100.
# 3.OA.7 Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.

We also will be practicing geometry.

# 3.MD.I Geometric measurement: understand concepts of area and relate area to multiplication and to addition.
# 3.MD.5 Recognize area as an attribute of plane figures and understand concepts of area measurement.
# 3.MD.5.a A square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area.

3.MD.5.b A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.

3.MD.7.a Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.

Practicing any of these skills will help tremendously.
