Represent numbers using base-ten blocks and draw beads on an abacus. Numbers up to 9999. Round to the nearest 1000.

Here are the solutions to the problems.

1. Fill in as shown.

• a) The image shows 2 thousands blocks, 3 hundreds flats, 1 tens rod, and 2 ones cubes.

  $$2000 + 300 + 10 + 2 = \boxed{\text{2312}}$$

• b) The image shows 3 thousands blocks, 3 hundreds flats, 3 tens rods, and 2 ones cubes.

  $$3000 + 300 + 30 + 2 = \boxed{\text{3332}}$$

• c) The image shows 3 thousands blocks, 3 green hundreds flats, 3 purple hundreds flats, 3 tens rods, and 2 ones cubes.

  $$3000 + 300 + 300 + 30 + 2 = \boxed{\text{3632}}$$

• d) The image shows 3 thousands blocks, 3 hundreds flats, 3 pink tens rods, 3 orange tens rods, and 2 ones cubes.

  $$3000 + 300 + 30 + 30 + 2 = \boxed{\text{3362}}$$

2. Draw beads to match the number.

• a) For the number 2341:

  • Thousands (Th): Draw 2 beads.
  • Hundreds (H): Draw 3 beads.
  • Tens (T): Draw 4 beads.
  • Ones (O): Draw 1 bead.

• b) For the number 5555:

  • Thousands (Th): Draw 5 beads.
  • Hundreds (H): Draw 5 beads.
  • Tens (T): Draw 5 beads.
  • Ones (O): Draw 5 beads.

• c) For the number 7408:

  • Thousands (Th): Draw 7 beads.
  • Hundreds (H): Draw 4 beads.
  • Tens (T): Draw 0 beads.
  • Ones (O): Draw 8 beads.

• d) For the number 9000:

  • Thousands (Th): Draw 9 beads.
  • Hundreds (H): Draw 0 beads.
  • Tens (T): Draw 0 beads.
  • Ones (O): Draw 0 beads.
