Product Description

This lesson covers Common Core Standard 4.NF.3a (Understand addition and subtraction of fractions by joining and separating parts referring to the same whole) and 4.NF.3b (Decompose a fraction into a sum of fractions...) and Oklahoma Academic Standard 4N.2.3 (Decompose a fraction in more than one way into a sum of fractions with the same denominator...). Through the use of pattern blocks, the students will identify the number of triangles it takes to create the entire hexagon, rhombus, etc. - determining the fractional part the triangle represents for each shape. After the students explore with the pattern blocks, the teacher will guide the discussion and model the lesson and assist the students in describing the process they use to compose and decompose the fractional parts of the whole in words. They will continue in small groups or large group. The students use the cloud on the first page to write what they know (their schema) about fractions before the lesson begins. They like to create a caricature of themselves to the left of their schema cloud. Hopefully, after the lesson they can add more details to their schema. This can be followed up with more practice with adding and subtracting fractions on worksheets, tests, etc., as well as leading into mixed numbers. You can copy this in black and white or in color. This should work well as a Common Core or OAS observation lesson. There are also 2 simple handouts included. Have a wonderful and successful year!!!
