In This Unit of Study…

Third graders will demonstrate understanding of place value up to 10,000. They will exhibit this by using concrete manipulatives, pictorial models, and numbers (including standard numbers, words, and expanded form). Students will need to understand that the value of a digit depends on its place or position in the number (place value).

3,704: In this example, the 7 is in the hundreds place and represents 7 hundreds or 700. Students will also need to use accurate place value language to read, write, and say numbers: “Three thousand, seven hundred four.” Notice that the word and is not used to describe 3,704. The word and is used when students describe fractions and decimal fractions such as one and one-half.

Students will use their knowledge of place value and place value language to add, subtract, multiply, and divide.
