I made these products to help address two standards my third graders always struggle with - 3.NF.2 (Fractions on a number line) and 3.NF.3c (express whole numbers as fractions and recognize fractions that are equivalent to whole numbers).
You could also use these resources for remediation or review at the beginning of a unit in 4th grade.
