Part 1 Directions:
- We built 1,463 with 1 thousand, 4 hundreds, 6 tens, and 3 ones, and we build 1,463 with 1 thousand, 0 hundreds, 46 tens, and 3 ones.
- What other ways can you build 1,463?
- Use the base ten blocks below to help you.
- In your journal, draw a model. Then complete the following for each: ___ thousands, ___ hundreds, ___ tens, ___ ones
Part 2 Directions:
- Open the interactive drawing link below, and make a copy.
- With a partner, play 4- Digit Number WAR.
- Each player will determine the value of the number represented by thousands, hundreds, tens, and ones. The player with the highest value in each "battle" wins.
- Use place value blocks to help you.

In Your Math Notebook:
Let’s get out our math journals and work through the following application problem. Make sure you read the problem carefully, draw a picture to match your thinking and write and solve an equation.
R (Read the problem carefully.) Jay and Bella visited a candy warehouse. Candy is sold in crates of 1000, boxes of 100, packages of 10, and single pieces of candy. Jay purchased 9 crates, 2 boxes, 7 packages, and 4 single pieces of candy. How many pieces of candy did Jay purchase? Bella purchased 8 crates, 9 boxes, 9 packages, and 1 single piece of candy. How many pieces of candy did Bella purchase? Compare the amounts each child purchased. Use >, =, or <. Tell how you know which child purchased the most candy. D (Draw a picture.) W (Write and solve an equation.) |
