Use this hands-on lesson to encourage collaboration amongst students as they review base-ten numerals, number names, and expanded form. This lesson can be used as a pre-lesson to Base Ten Block Party or as a stand-alone activity.
Students will be able to read and write numbers to 1,000.
Students will be able to ask clarifying questions with content specific vocabulary in order to write numbers to 1,000 in base-ten, expanded, and written form using partnerships and sentence frames for support.
Bring the students together and write the following information on the whiteboard:
1000 + 200 + 30 + 8
One thousand two hundred thirty eight
Create a word bank next to the information (draw a circle around the word bank to separate it from the information) with the words base-ten numeral, number name, and expanded form.
Explain to the students that in mathematics, we can show numbers in different ways.
Read through the words in the word bank and explain that each of the words represents a way in which we can show numbers.
Instruct the students to complete a think-pair-share, matching the information on the whiteboard to the words in the word bank.
Allow a partnership to come up to the board to correctly label the information. Ask the other students in the classroom to stand up if they agree, and to stay seated if they disagree. Do not clarify the correct information, as you will get to this after introducing the vocabulary words for the lesson.
Explain to the students that today they will be learning how to write numbers in base-ten numerals, using number names, and also expanded form.
