Tell students that the symbol for drawing a big cube is .
Students work to independently complete 2.5.5 Math Message. (5 min.)
Go over the answers as a whole class. Model the statements of equality with the base10 blocks. (5 min.)
2. Reading, Writing, and Showing Numbers in the Thousands (30 min.)
Flexible Practice:
Use some of the following activities to help your students develop an understanding and fluency with numbers in the thousands.
See the 2.5.5 Teacher Reference page for many examples of ways to have students develop an understanding and fluency with place value in the thousands. Many of these tasks can be completed in whole group practice, small group work, partner work, or 1:1.
For these activities, students will need base10 blocks, place value mats, slates, number cards, etc. Students can also use the class place value flip chart to display numbers.
There are 3 different worksheets A, B, and C to choose from.
3. Math Workout (15 min.)
Students complete 2.5.5 Math Workout
4. Summary (5 min.)
How do mathematicians read, write, and represent numbers in the thousands?
