2. On a rainy day, Greg decided to build a LEGO castle.

3. On a rainy day, Greg decided to build a LEGO castle. He thinks that the drawbridge and the foundation are the best places to start.

4. On a rainy day, Greg decided to build a LEGO castle. He thinks that the drawbridge and the foundation are the best places to start. For the foundation, Greg will need to connect two flat blocks together.

5. On a rainy day, Greg decided to build a LEGO castle. He thinks that the drawbridge and the foundation are the best places to start. For the foundation, Greg will need to connect two flat blocks together. The bottom block will be one less than the top block.

6. Think to yourself about about the next question. The bottom block will be one less than the top block. If this was the top block, how many “nubs” would the bottom block have? How did you decide how many “nubs” the block on the bottom would have?

7. For the drawbridge, Greg will connect two blocks together again. In this case, the bottom block is two less than the top block.

8. Think to yourself about about the next question. The bottom block will be two less than the top block. How did you decide how many “nubs” the block on the bottom would have? If this was the top block, how many “nubs” would the bottom block have?

9. Below is a list of the lengths of top blocks Greg will need for each part of the castle. Find the length of the bottom blocks that go with each top block.

10. Below is a list of the lengths of top blocks Greg will need for each part of the castle. In your journal find the length of the bottom blocks that go with each top block. Foundation Top Block - remember that the bottom block is 1 less than the top block. Drawbridge Top Block - remember that the bottom block is 2 less than the top block. 11 nubs 10 nubs 8 nubs 7 nubs 5 nubs 4 nubs 2 nubs 12 nubs 11 nubs 9 nubs 7 nubs 6 nubs 4 nubs 3 nubs MAKE SURE THAT YOU CAN PROVE YOUR SOLUTIONS. YOU SHOULD USE PICTURES, NUMBERS, AND WORDS TO EXPLAIN YOUR SOLUTION.
