This past week, students worked on adding and subtracting fractions with different denominators. This week, we will continue working on adding and subtracting fractions, but ones with larger denominators and problems with multiple steps. We will also review for the Topic test which is slated for Thursday, but if we still need more time, will occur on Monday, May 22nd. Progress reports will be sent out by the end of the week.

Last week, we mastered finding the least common denominator of fractions and began adding fractions with different denominators. This week, we will complete the lesson on adding fractions and master subtracting fractions with different denominators. We are coming to the end of this unit, so expect a test next week.
Last week, we looked at common and least common multiples of two or three different numbers. This week, we will apply that skill to find the least common denominators of two and three different fractions to add them together. We are quickly coming to the end of this unit on fractions and will have the unit test next week probably on Wednesday or Thursday.
Last week, we reviewed a little bit on estimating fractions. When we estimate them, we look to see if the fraction is closest to 0, 1/2, or 1 whole. These are the only three items we estimate fractions to, and the way we do it is compare the numerator to the denominator. If the numerator is about half of the denominator, we would estimate it to 1/2. If the numerator is almost zero compared to the denominator or almost all of the denominator, we would estimate the fraction to either zero or 1 whole. Later this week, we will look at finding common multiples, especially least common multiples, and then we will practice finding common denominators of fractions.
Last week, students spent a lot of time trying to estimate fractions in order to add or subtract them. It got a little tricky for them to estimate to the nearest 0, 1/2, or 1. We will spend a little more time on this to start the week, and then move directly into adding and subtracting fractions with the same denominator.
