This worksheet is designed to help students understand place value up to hundreds using base-10 blocks. Base-10 blocks are a visual and tactile tool used to represent numbers, where:
-
Large squares represent
hundreds (100 each).
-
Tall rectangles represent
tens (10 each).
-
Small cubes represent
ones (1 each).
We will count the number of blocks in each set and write down the total number.
Solution:
#### 1)
-
Hundreds: 1 large square = 100
-
Tens: 4 tall rectangles = 4 × 10 = 40
-
Ones: 0 small cubes = 0
-
Total: 100 + 40 + 0 =
140
#### 2)
-
Hundreds: 2 large squares = 2 × 100 = 200
-
Tens: 0 tall rectangles = 0
-
Ones: 5 small cubes = 5
-
Total: 200 + 0 + 5 =
205
#### 3)
-
Hundreds: 1 large square = 100
-
Tens: 5 tall rectangles = 5 × 10 = 50
-
Ones: 6 small cubes = 6
-
Total: 100 + 50 + 6 =
156
#### 4)
-
Hundreds: 2 large squares = 2 × 100 = 200
-
Tens: 1 tall rectangle = 1 × 10 = 10
-
Ones: 2 small cubes = 2
-
Total: 200 + 10 + 2 =
212
#### 5)
-
Hundreds: 0 large squares = 0
-
Tens: 0 tall rectangles = 0
-
Ones: 5 small cubes = 5
-
Total: 0 + 0 + 5 =
5
#### 6)
-
Hundreds: 2 large squares = 2 × 100 = 200
-
Tens: 9 tall rectangles = 9 × 10 = 90
-
Ones: 0 small cubes = 0
-
Total: 200 + 90 + 0 =
290
#### 7)
-
Hundreds: 3 large squares = 3 × 100 = 300
-
Tens: 4 tall rectangles = 4 × 10 = 40
-
Ones: 5 small cubes = 5
-
Total: 300 + 40 + 5 =
345
#### 8)
-
Hundreds: 5 large squares = 5 × 100 = 500
-
Tens: 4 tall rectangles = 4 × 10 = 40
-
Ones: 3 small cubes = 3
-
Total: 500 + 40 + 3 =
543
