##### Presentation Transcript

1. Find the Block We looked very closely at the faces of the Geoblocks yesterday. This card shows all the faces of one Geoblock, and was made by tracing around each face. Can you figure out by looking at this card how many faces or sides the Geoblock had?

2. Find the Block • Number of sides? • Now select the Geoblock that Task Card 1 represents. • See how every face of the block can be matched to one of the outlines on the card. • Each card represents only one block.

3. Find the Block • This activity is called Find the Block. In Math Workshop, you will work with a partner to Find the Block. • There are 4 students at each station. Each station has Geoblocks and two decks of Task Cards. One pair will work with Task Cards 1-6 and the other will work with Task Cards 7-12.

4. Decide with your partner which card to work on and try to find the block that matches that card. Once you have each found a block, compare them and then prove to each other that yours is the correct block by showing how each side matches the outlines on the card.

5. Math Tools • One of the math tools that we will be using during our geometry unit is the computer. • Many of you have already used a computer and done different types of activities on the computer when we go to the computer lab.

6. Shapes • You will work with a partner and will build pictures and designs with Shapes just the way they did with pattern blocks in the previous unit. Shapes CD

7. Drawing Geoblocks • You will build your own construction from the Geoblocks. • Then you will draw your construction from different angles.

8. Double Arrays I picked a 3 3 + 3 = 6

9. The Match Game Match the 3-D block to the 2-D face.
