Prior to beginning the lesson: (1) Photocopy the Problem of the Day
onto transparency paper for the overhead projector; (2) Photocopy One-Half Practice Sheet
(1 per student).
Students will be able to:
Materials:Problem of the Day
(see attachment), “Fractions Around Us” Chart (from Lesson #2), Give me Half
by Stuart J. Murphy, One-Half Practice Sheet
(see attachment), crayons, overhead projector
Lesson Introduction: Display Problem of the Day
on the overhead projector. Ask students: What strategy should we use to solve this problem?
Guide them towards draw a picture. Solve the problem together as a class. Students can copy problem and solution into math notebooks.
Review the chart “Fractions Around Us” from the previous day. If students have any other ideas, add them to the list.
Read the story Give me Half by Stuart J. Murphy out loud to the class. Ask students: What else can we cut in half or fold in half?
Write the number "1/2" on the board. Ask students: Do you remember how we read this? Write the word "half" on the board. Ask students: Can anybody read this word? Write the word "one-half" on the board. Ask students: Can anybody read this word? Explain to students: 1/2, half, and one-half are all used in the same way. Half and one-half are the same, and you will hear it said both ways.
Tell students: Today, you are going to practice showing one-half. Distribute One-Half Practice Sheet and give direction orally. Allow students time to work independently.
Modifications: For students with special needs, allow extra time to answer questions and provide one-on-one assistance when necessary.
Teacher should monitor independent work to ensure all students are understanding the concept.
Benchmark or Standards:
