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.
5th Grade News
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.
Prior to break, students learned how to simplify fractions and make estimates on fractional parts of diagrams. This week, students will look at using estimation to solve fraction addition and subtraction problems. After that, students will be solving fraction addition and subtraction problems using a common denominator. Students will be receiving progress reports this week as grades will be updated. Please ask for these from your child if you did not see it by Wednesday.
Last week, we completed our previous unit by taking the unit test and started our next unit on adding and subtracting fractions. We first reviewed how to calculate equivalent fractions by multiplying or dividing both the numerator and denominator by the same number. We then looked at how to simplify fractions using division and the greatest common factor. This week, we will continue looking at simplifying fractions, making an estimation of fractions represented by pictures and diagrams, and then using estimation to complete the addition and subtraction of fractions. There will be no progress reports early this week, but I will send some home on Friday before spring break.
Students finished their Topic 4 Unit and will be taking the test this week. The next unit will be on adding and subtracting fractions which will begin on Wednesday. All late, corrected, and make-up work has been graded and placed into the grade book. There will be no new scores for this quarter entered this week, but the work completed this week will go to the 4th quarter grades.
