**4.1-Unit 3 Exploring Equivalence and Ordering of Fractions**This week, students will continue working on standard 4.NF.2. They will explore different models (fraction bars, fraction circles, number lines) for comparing fractions with both like and unlike denominators. They will also learn how to compare fractions by finding a common denominator.

As students become more comfortable with their learning goals and the activities they are completing to achieve their goals, they have begun taking the quizzes to confirm their mastery. Some students are at this point and we suspect many others will be taking quizzes this week. We have also told the students that

**the goal to complete this unit and to take a test will be next Wednesday, December 18. The Unit 3 Study Guide will be sent home this Wednesday, December 12.**Homework

__4.1 Standards for the Week:__4.NF.2 - Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

__4.2-Unit 7: Measurement and Data__Students are working towards mastery of their learning goals with Area and Perimeter this week. On Thursday and Friday, students will be introduced to interpreting and analyzing data on a line plot graph.

As students become more comfortable with their learning goals and the activities they are completing to achieve their goals, they have been advised to ask for a quiz to confirm their mastery. Many students are at this point with area and perimeter and I suspect many will be taking a quiz this week. I have also told the students that

__4.2 Standards for the Week:__*4.MD.1: Know relative sizes of measurement units within one system of units including km, m, cm; kg, g, lb, oz; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table.*

4.MD.3: Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.

4.MD.4: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in the line plots.

**5.1-Unit 2: Subtracting Fractions**We will be reviewing adding and subtracting fractions this week. We will be having a test covering 5.NF.1 and 5.NF.2.

Thursday - Complete Study Guide and Review; Test on Friday

__5.1 Standards for the Week:__

*5.NF.1:**Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators.*

*5.NF.2:**Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers.*
