**4.1-Unit 3 Exploring Equivalence and Ordering of Fractions**This week, students will continue working on standard 4.NF.2 and will be reviewing 4.NF.1. 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 19. The Unit 3 Study Guide will be sent home this Wednesday, December 12.**Homework

Tuesday: Complete and Review Study Guide: Test on Wednesday that will cover Mastered Standards

Thursday - No HW; Happy Holidays

__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 Line Plots this week. Students were introduced to Interpreting Line Plots last week. This week, students are creating, interpreting, and analyzing information for a line plot.

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. All students have completed an Area and Perimeter quiz at this point. There will not be a quiz covering line plots, but it will be addressed on the test. I have also rescheduled the test for this unit to be on Wednesday, December 19, instead of Tuesday, December 18.

Thursday: No HW; Happy Holidays!

__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.

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 3: Multiplying and Dividing Fractions**Students took a test covering adding and subtracting fractions last week. This week, they will begin a brief introduction to multiplying and dividing fractions.

**Homework:**

Tuesday – iReady Math (20 minutes)

Thursday - No HW; Happy Holidays

__5.1 Standards for the Week:__

__5.NF.3:__Apply and extend previous understandings of multiplication and division.

*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.*
