Current Math Unit: |
Parts of a Whole, Parts of a Group |
In this unit students learn that fractions are used to represent equal parts of whole objects such as a rectangle, a sandwich, or a ball of clay.
Students work with unit fractions (1/2, 1/3, 1/4), which represent one part of a whole, and they work with fractions such as 2/3, 2/4, 3/4 that represent more than one part of a whole. For example, when looking at a rectangle that is divided into four equal parts---three of which are shaded orange---students learn that three fourths comprises three of four equal parts.
Students will also learn how fractions are expressed in words (one half, two thirds) and represented with numbers (1/2, 2/3). Students will use fractions in different contexts including folding paper squares, coloring rectangles, and sharing sets of objects among a different number of people. Students will come to understand that the bottom number, denominator, represents the number of equal parts in the whole.
We have been discussing in class how fractions must be equal or fair! Talk with your child about this at home, often times the kitchen presents a great opportunity to do this when splitting food!
Here is a helpful video that discusses partitioning shapes into halves and thirds: www.youtube.com/watch?v=6ooKWyPI0i4
For review of our previous unit: How many tens? How many ones?
We have been working on ways to make 100 and 1.00. This is something very simple you can practice with your child at home by using the change you receive at the store. Encourage your child to show you different strategies they have learned to add and subtract. Though they may be comfortable with one way it is very beneficial for them to master more than one strategy!
Here is a link to the different types of word problems your child will see in 2nd grade: www.youtube.com/watch?v=_HWxAqRpXug
