Math 3rd Grade Trimester 3 Claudio Serrano 2019-2020

1. Unit 11: Fractions

   • L.E.: Students will understand that fractions are equal parts of a whole and what the numerator and denominator of a fraction represent. This sets the foundation for understanding equivalent fractions and how they are formed. they will learn to add and subtract related fractions which need to be converted to like fractions through forming equivalent fractions. Finally they will learn that the fractional answer is only complete when it is expressed in its simplest form.
     • Lesson 1: Fractions of a whoile
       • Group Activity: Written Practice MAR 17-20
       • Practice: Naming fractions MAR 17-20
     • Lesson 2: Equivalent fractions
       • Activity: Expressing fractions in its simplest form MAR 24-27
     • Lesson 3: Adding fractions
       • Practice: Adding fractions . MAR 24-27
       • Quiz: Adding fractions . MAR 24-27
     • Lesson 4: Subtracting fractions
       • Practice: Fraction circles group MAR 30-APR 3
       • Quiz: Subtracting fractions . MAR 30-APR 3

2. Unit 12: Time

   • L.E.: Students will learn how to tell time using a clock face by 1-minute intervals. They will use their knowledge of using a.m. and p.m. in telling time to calculate durations of time with start times in a.m. and end times in p.m., or vice versa. Students will understand the relationships between hours and minutes, years and months, as well as week and days as it forms the foundation for converting between different units of time. They will work timeline as a useful tool to present and solve problems involving time.
     • Lesson 1: Hours and minutes
       • Activity: Expressing time . APR 13-17
     • Lesson 2: Other units of time
       • Practice: Expressing days, months and years . APR 13-17
       • Quiz: Telling time . APR 20-24

3. Unit 13: Geometry

   • L.E.: Students will learn about angles, defined as being formed by two rays or line segments with a common endpoint. Students will learn to identify and compare angles, right angles and to compare the size of angles with respect to a right angle.
     • Lesson 1: Angles
       • Practice: Identifying parts of an angle . APR 27-30
       • Group activity: Identifying different types of angles . MAY 4-8
     • Lesson 2: Right angles
       • Quiz: Types of angles . MAY 4-8

4. Unit 15: Area

   • L.E.: Students will learn that the area of a figure can be found by counting the nunber of unit squares (or half-squares) that are needed to cover the surface of the figure. they will also learn two common units of measure of area - square centimeter and square meter, and learn to visualize their relative sizes.
     • Lesson 1: Square units
       • Practice: Measure square units
       • Classwork: Comparing areas of different figures . MAY 26-29
     • Lesson 2: Area in square centimeters and square meters
       • Quiz: Measuring area . JUNE 1-5
       • Practice: Measuring areas with centimeters and meters . JUNE 1-5

5. Unit 14: Perpendicular and parallel lines

   • L.E.: Students will learn to identify perpendicular and parallel line segments. They will use the skill of identifying a right angle to help them identify perpendicular line segments. Students will also learn to draw perpendicular and parallel lines on square grids.
     • Lesson 1: Perpendicular line segments
       • Practice: Drawing perpendicular lines
     • Lesson 2: Parallel line segments
       • Classwork - quiz: Identify and draw parallel and perpendicular lines
     • Lesson3: Horizontal and vertical line segments
       • Practice: identifying types of lines in school structures
