Description
Small Groups Instruction Number Lines and Area Models
Students can use these number lines and area models to find equivalent fractions, add and subtract and estimation.
How to Use the Cards:
Print the cards on cardstock, cut and laminate. Use in small group instruction with manipulatives to help students make a connections and increase their understanding of fractions.
Skills:
Number and operations. The student applies mathematical process standards to represent and generate fractions to solve problems. The student is expected to:
- 4.3(A) represent a fraction a/b as a sum of fractions 1/b, where a and b are whole numbers and b > 0, including
- when a > b
- 4.3(B) decompose a fraction in more than one way into a sum of fractions with the same denominator using
- concrete and pictorial models and recording results with symbolic representations
- 4.3(C) determine if two given fractions are equivalent using a variety of methods
- 4.3(D) compare two fractions with different numerators and different denominators and represent the comparison using the symbols >, =, or <
- 4.3(E) represent and solve addition and subtraction of fractions with equal denominators using objects and pictorial models that build to the number line and properties of operations
- 4.3(F) evaluate the reasonableness of sums and differences of fractions using benchmark fractions 0, 1/4, 1/2, 3/4, and 1, referring to the same whole
- 4.3(G) represent fractions and decimals to the tenths or hundredths as distances from zero on a number line
