Educational math worksheet for building two-digit numbers using base ten blocks with construction vehicle themes.

This is a worksheet for building two-digit numbers using base ten blocks. The task is to draw the correct number of tens and ones blocks in each box to represent the given number.

Here is the solution for each problem:

- A (42): Draw 4 ten-blocks and 2 one-blocks.
- B (84): Draw 8 ten-blocks and 4 one-blocks.
- C (75): Draw 7 ten-blocks and 5 one-blocks.
- D (59): Draw 5 ten-blocks and 9 one-blocks.
- E (27): Draw 2 ten-blocks and 7 one-blocks.
- F (36): Draw 3 ten-blocks and 6 one-blocks.
- G (91): Draw 9 ten-blocks and 1 one-block.
- H (13): Draw 1 ten-block and 3 one-blocks.
- J (44): Draw 4 ten-blocks and 4 one-blocks.

Each number is composed of a tens digit and a ones digit. The tens digit tells you how many groups of ten (represented by long rectangular blocks) to draw, and the ones digit tells you how many single units (represented by small squares) to draw.
