To solve this problem, we need to count the value of the Base Ten blocks in each picture.
Remember the rules for Base Ten blocks:
*
Small single cube = 1 (One)
*
Long rod (made of 10 cubes) = 10 (Ten)
*
Flat square (made of 10x10 cubes) = 100 (Hundred)
Here is the step-by-step counting for each card:
Card 1: The Sun
*
Flats: There is 1 large yellow square in the center. Value: $1 \times 100 = 100$.
*
Rods: There are 8 rods sticking out like rays. Value: $8 \times 10 = 80$.
*
Units: Inside the flat square, there are small red cubes. Counting them carefully, there are 9 red cubes. Value: $9 \times 1 = 9$.
*
Total: $100 + 80 + 9 = 189$.
Card 2: The Fish
*
Flats: There is 1 large green square for the body. Value: $1 \times 100 = 100$.
*
Rods:
* Tail: 3 green rods.
* Ground/Seaweed stem: 1 brown rod.
* Seaweed leaves: 2 green rods.
* Total Rods: $3 + 1 + 2 = 6$ rods. Value: $6 \times 10 = 60$.
*
Units:
* Bubbles: 3 blue cubes.
* Fins: 4 pink cubes.
* Seaweed tips: 2 green cubes.
* Total Units: $3 + 4 + 2 = 9$ units. Value: $9 \times 1 = 9$.
*
Total: $100 + 60 + 9 = 169$.
Card 3: The Octopus/Jellyfish
*
Flats: There is 1 large purple square for the head. Value: $1 \times 100 = 100$.
*
Rods: There are 7 tentacles hanging down. Each is a rod. Value: $7 \times 10 = 70$.
*
Units: Inside the head, there are small blue cubes forming a smiley face. Let's count them: 2 eyes, 1 nose, and a mouth made of 5 cubes. Total: $2 + 1 + 5 = 8$ units. Value: $8 \times 1 = 8$.
*
Total: $100 + 70 + 8 = 178$.
Card 4: The Kite
*
Flats: There is 1 large red square for the kite body. Value: $1 \times 100 = 100$.
*
Rods: Look at the tail. It is made of alternating colors. There are 5 rods in the tail. Value: $5 \times 10 = 50$.
*
Units:
* Pattern on the kite: There are 8 blue cubes arranged in an 'X'.
* Connectors on the tail: There are 4 small cubes connecting the rods.
* End of the tail: There is 1 black cube at the very end.
* Total Units: $8 + 4 + 1 = 13$ units.
*
Total: $100 + 50 + 13 = 163$.
Card 5: The House
*
Flats: The main walls are made of gray flats. There are 2 large gray squares side-by-side. Value: $2 \times 100 = 200$.
*
Rods:
* Roof: 2 brown rods.
* Chimney: 1 red rod.
* Grass/Ground: 1 long green strip (it looks like a rod).
* Total Rods: $2 + 1 + 1 = 4$ rods. Value: $4 \times 10 = 40$.
*
Units:
* Windows: 4 white cubes.
* Door: 4 black cubes.
* Total Units: $4 + 4 = 8$ units. Value: $8 \times 1 = 8$.
*
Total: $200 + 40 + 8 = 248$.
Final Answer:
1. 189
2. 169
3. 178
4. 163
5. 248
