Colleen老師的三年級數學課：分數

This unit’s focus is on fractions.  Students will focus on  dividing fractions into equal parts of a whole, counting and modeling fractions, placing fractions on number lines, making equivalent fractions and comparing fractions. Lessons will be displayed using powerpoint or google slides.  Students should have a good understanding of grade 2 fraction concepts before taking this course.  Students should also have an understanding of 2 digit by 1 digit multiplication and division as our warm ups will include this.  Students are encouraged to use manipulatives throughout the unit. I will include a paper copy of manipulatives.   Please take a look at the following description below to see if this class is a good fit for your learner. 
 
Each lesson will have the same format: 
Warm up: we will do a math warm up to help turn on our minds to get ready for the lesson. A math question(s) will be displayed on a google slide. Students can record their thinking on a worksheet. Students are encouraged to share their thinking with the class. Our warm ups are focused on 2 digit by 1 digit Multiplication and Division.
Lesson: I will teach a lesson to the class. We will work together using anchor charts, manipulatives and powerpoint presentations. Students will “Watch Me First”, explaining a concept and work through a problem. Then through guided practice, students will work through the material with me. Students will be provided with a worksheet to record their thinking as we engage in the lesson. I will be using digital manipulatives.
 Independent work: Students will work on assigned work with support from me. Students will be provided with a worksheet. We will go over the work together.  Students are encouraged to share their thinking with the class.
Game or activity to support the concepts learned in class.
Reflection: Students will reflect on their thinking and how they feel about the math topic.
Extension: Students will be provided with an extension activity that he or she can complete on their own time.  Extension activities are a support for learning outside of class time.  These activities are not evaluated by me.
 
Lesson 1 - Partition Fractions
Objective: Learners will practice partitioning shapes into equal parts (halves, thirds, fourths, sixths and eighths). For example: determining if a shape (square, rectangle, triangle, circle) is divided into equal or unequal parts, dividing a square into halves to sixths, showing different ways to divide a square into fourths. 
Manipulatives: Extra copy of shapes to cut into parts or draw lines on.
Activity: Snowman Fraction: please have a piece of white paper, a piece of construction paper or coloured paper, something to colour with. 
 
Lesson 2 - Unit Fractions
Objective: Learners will practice counting and modeling unit fractions with fraction strips. For example: learners will use fractions strips to represent one-whole, halves, thirds, fourths, sixths and eighths.
Manipulatives: Fraction strips
Activity: Fraction Robot: please have scissors, glue, pencils and something to colour with on hand.
 
Lesson 3 - Non - Unit Fractions
Objective: Learners will practice naming and modeling non-unit fractions. For example: Jill bought a pie. She cut it into 8 equal pieces.  She enjoyed eating 3 pieces of the pie. What fraction of the pie did she eat? Writing a fraction of a shaded part of a triangle, what is the denominator and what is the numerator?
Manipulatives: Fraction builder mat, tiles
Activity: Fraction Circles, coloured paper or construction paper, something to trace a circle with, scissors, glue, pencil.
 
Lesson 4 - Number Lines
Objective: Learners will practice dividing number lines into equal parts and placing different fractions on the number line. For example: dividing a fraction strip on a number line into 3 equal parts, placing a missing fraction on a number line.
Manipulatives: Fraction number line mat, tiles
Activity: Fraction Number Line Art: please have a piece of white paper, something to colour with and a pencil.
 
Lesson 5 - Placing Fractions On Number Lines
Objective: Learners will practice finding and placing fractions, less than 1, on a number line. For example: the mall is two sixths of a mile from Sam’s house. Draw where the mall would be on the given number line.
Game: Fraction Tic Tac Toe
 
Lesson 6 - Placing Fractions On Number Lines Continued
Objective: Learners will practice finding and placing fractions, greater than 1, on a number line. For example: Each day, Frank walks to school. There is an Ice Cream Stand 2 miles away from his house.  How far does Frank walk to school? Students will use a given number line with information on it to help solve the problem.
Manipulatives: Fraction Number line, tiles
Activity: Fraction Flowers
 
Lesson 7 - Equivalent Fractions
Objective: Learners will practice finding equivalent fractions with models. For example: shade in part of a given rectangle to determine the equivalent fraction to one half. 
Manipulatives: Fraction Builder Mat, tiles
Activity: Equivalent Fraction Pizza. Please have construction paper or coloured paper, a piece of white paper, something to colour with, scissors, glue, pencil.
 
Lesson 8 - Equivalent Fractions On A Number Line
Objective: Learners will practice finding equivalent fractions with number lines. For example: using a number line to determine the equivalent fraction ⅔ and ?/6 using a given number line.
Manipulatives: Equivalent Fraction Mat, tiles
Game: Roll And Cover - Please have 2 dice
 
Lesson 9 - Comparing Fractions
Objective: Learners will practice comparing two fractions that have the same denominator. For example: comparing 2/4 to ¾ using the less than, greater than or equal symbol and shading in these fractions on a fraction strip.
Manipulatives: Comparing Fractions Mat, tiles
Game: Student Vs Teacher Fraction Game
 
Lesson 10 - Comparing Fractions Continued
Objective: Learners will practice comparing two fractions that have the same numerator. For example: comparing ½ to ¼  using the less than, greater than or equal symbol and shading in these fractions on a fraction strip.
Manipulatives: Equivalent Fraction Mat, tiles
Game: Know or Go Students Vs Teacher
