Sample Layout:
       1  1
       3  7  8
    +  2  4  5
    ----------
       6  2  3

Problem Set 1

Problem 1A: Write the number 734 in expanded form and in word form. Problem 1B: Compare 648 and 684 using the correct symbol (<, >, or =). Problem 1C: Solve 458 + 276 using the standard vertical addition algorithm with double regrouping. Problem 1D: Solve 600 - 347 using the standard algorithm across zeros or the subtract-one shortcut. Problem 1E: Round the number 476 to the nearest ten and state the bounding tens.

Practice Section 2: Equal Groups and Arrays

Translate each visual scenario into repeated addition and equal groups sentences.

Sample Array (2 by 4):
*  *  *  *
*  *  *  *
Row Equation: 4 + 4 = 8
Col Equation: 2 + 2 + 2 + 2 = 8

Problem Set 2

Problem 2A: Write a repeated addition equation for 4 bowls containing 5 apples each, and state the total. Problem 2B: An array has 3 rows with 4 circles in each row. Write both the row repeated addition equation and the column repeated addition equation. Problem 2C: Share 18 colored beads equally among 3 children. How many beads does each child receive?

Practice Section 3: Money and Time

Read clock displays and count coin collections carefully from largest to smallest.

Sample Clock:
Hour hand between 6 and 7; Minute hand at 5 (25 minutes).
Time: 06:25

Problem Set 3

Problem 3A: Count the total value of 2 quarters, 3 dimes, 1 nickel, and 4 pennies in both cent and dollar notation. Problem 3B: An analog clock shows the hour hand between 2 and 3, and the minute hand pointing directly at 9. Write the time in digital notation and state how to read it using the word "quarter." Problem 3C: You buy a bookmark for 43c and pay with two quarters (50c). How much change do you receive?

Practice Section 4: Measurement and Geometry

Use your knowledge of linear units and geometric attributes to solve each problem.

Sample Polygon:
Pentagon: 5 straight sides, 5 vertices, 5 angles.

Problem Set 4

Problem 4A: A green ribbon is 54 cm long and a yellow ribbon is 37 cm long. How much longer is the green ribbon? Problem 4B: Name the 3D solid figure that has exactly 6 identical square flat faces, 12 edges, and 8 vertices. Problem 4C: A rectangle is partitioned into 3 rows and 4 columns of same-size squares. How many total unit squares tile the rectangle? Write the row addition equation.

Complete Answer Keys and Step-by-Step Solutions

Solution to Problem 1A: Expanded form of 734 is 700 + 30 + 4. Word form is seven hundred thirty-four.

Solution to Problem 1B: The statement is 648 < 684. Both have 6 hundreds, but 648 has 4 tens while 684 has 8 tens. Since 4 tens is less than 8 tens, 648 is less than 684.

Solution to Problem 1C: For 458 + 276: Add ones: 8 + 6 = 14 (write 4, carry 1 ten). Add tens: 1 + 5 + 7 = 13 tens (write 3, carry 1 hundred). Add hundreds: 1 + 4 + 2 = 7 hundreds. The sum is 734.

Solution to Problem 1D: For 600 - 347 using subtract-one shortcut: 599 - 346. Ones: 9 - 6 = 3. Tens: 9 - 4 = 5. Hundreds: 5 - 3 = 2. The difference is 253.

Solution to Problem 1E: For 476, the bounding tens are 470 and 480. Because the ones digit is 6 (which is 5 or more), round up to 480.

Solution to Problem 2A: For 4 bowls with 5 apples each: 5 + 5 + 5 + 5 = 20 apples in total.

Solution to Problem 2B: For an array with 3 rows of 4: Row equation is 4 + 4 + 4 = 12. Column equation (4 columns of 3) is 3 + 3 + 3 + 3 = 12. Total is 12 circles.

Solution to Problem 2C: Dividing 18 beads equally among 3 children: 18 / 3 = 6 beads per child (since 6 + 6 + 6 = 18).

Solution to Problem 3A: Count coins from largest to smallest: 2 quarters (50c), 3 dimes (60c, 70c, 80c), 1 nickel (85c), 4 pennies (86c, 87c, 88c, 89c). Total is 89c or $0.89.

Solution to Problem 3B: Digital time is 02:45. In words using "quarter", it is read as "quarter to three" (or "two forty-five").

Solution to Problem 3C: Two quarters equal 50c. Subtract: 50c - 43c = 7 cents change (or count up from 43 to 50: 43 + 7 = 50c).

Solution to Problem 4A: Subtract 54 cm - 37 cm. Regroup 1 ten: 14 - 7 = 7 ones, 4 tens - 3 tens = 1 ten. The green ribbon is 17 centimeters longer.

Solution to Problem 4B: A cube is the 3D solid figure with 6 identical square faces, 12 straight edges, and 8 vertices.

Solution to Problem 4C: A rectangle with 3 rows and 4 columns contains 4 + 4 + 4 = 12 unit squares.
