Title: LESSON 4: Improper Fractions and Mixed Numbers
Lesson Overview: Students will learn that an improper fraction is a fraction with a numerator that is larger than the denominator and that a mixed fraction is a whole number and a proper fraction. Students will be able to write an improper fraction as a mixed fraction and a mixed fraction as an improper fraction. They will learn how to add and subtract improper and mixed fractions.
Resources or Materials Needed:
Teachers: Activboard Improper and Mixed Fractions Lesson, computer, Elmo (document camera), example of Improper and Mixed Fractions foldable, class blog
Students: math toolkit, individual whiteboard, marker and eraser, student worksheet and guided notes, scissors, markers, foldable, manipulatives, calculator, iPad
Technology: class blog, YouTube, iPad game
Lesson Standards:
USOE Mathematics Fourth Grade Number and Operations 3.a:
