Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 4. Students use measurement contexts to support adding, subtracting, multiplying, and dividing with whole numbers as well as with simple fractions and decimals. It's important that they solve word problems related to measurement contexts that they're familiar with. More specifically, appropriate measurement contexts include length (inches, feet, centimeters, and meters), time, and money (whole number quantities like $3, 5 dimes, 13 cents), which students learned in Grade 2.*Teacher Advisor is 100% free.
