Use multiple-base materials to model the given numbers.

To model the given numbers using multiple-base materials (base-ten blocks), we break down each number into its place value components.

Step 1: Model 143000 $143000 = 1 \times 100000 + 4 \times 10000 + 3 \times 1000$ This means: • 1 hundred thousand block • 4 ten thousand blocks • 3 thousand blocks • 0 hundred flats • 0 ten rods • 0 unit cubes The model for 143000 is: $\boxed{1 hundred thousand, 4 ten thousands, 3 thousands}$

Step 2: Model 327000 $327000 = 3 \times 100000 + 2 \times 10000 + 7 \times 1000$ This means: • 3 hundred thousand blocks • 2 ten thousand blocks • 7 thousand blocks The model for 327000 is: $\boxed{3 hundred thousands, 2 ten thousands, 7 thousands}$

Step 3: Model 361000 $361000 = 3 \times 100000 + 6 \times 10000 + 1 \times 1000$ This means: • 3 hundred thousand blocks • 6 ten thousand blocks • 1 thousand block The model for 361000 is: $\boxed{3 hundred thousands, 6 ten thousands, 1 thousand}$

Step 4: Model 112000 $112000 = 1 \times 100000 + 1 \times 10000 + 2 \times 1000$ This means: • 1 hundred thousand block • 1 ten thousand block • 2 thousand blocks The model for 112000 is: $\boxed{1 hundred thousand, 1 ten thousand, 2 thousands}$

Step 5: Model 237000 $237000 = 2 \times 100000 + 3 \times 10000 + 7 \times 1000$ This means: • 2 hundred thousand blocks • 3 ten thousand blocks • 7 thousand blocks The model for 237000 is: $\boxed{2 hundred thousands, 3 ten thousands, 7 thousands}$
