Example
Comparing & Ordering Decimals: Order from least to greatest: 2.74, 2.5, 2.9
Answer: 2.5, 2.74, 2.9

💡 Multiply as whole numbers: 2 × 5 = 10. 0.2 has 1 decimal place and 0.5 has 1 decimal place, so the product has 2: 0.10 = 0.1.
✓ Correct!

💡 Multiply as whole numbers: 2 × 5 = 10. 0.2 has 1 decimal place and 0.5 has 1 decimal place, so the product has 2: 0.10 = 0.1.
💡 How to solve: Multiplying Decimals Less Than 1 (Tenths × Tenths)
Multiply the digits as whole numbers (0.3 × 0.7 → 3 × 7 = 21). Add the decimal places of both factors (1 + 1 = 2) and give the answer that many: 0.21. If there are not enough digits, write zeros in front: 0.04 × 0.2 → 4 × 2 = 8, 3 places → 0.008.

Not quite. The answer is
💡 The digits are the same, but the decimal point moved 1 place to the right from 9.9 to 99. Moving it 1 place to the right means multiplying by a 1 with 1 zero: 10. Check: 9.9 × 10 = 99. The missing number is 10.

💡 How to solve: Multiplying Decimals by 10, 100 & 1,000
Multiplying by 10 moves every digit one place to the left, so the decimal point moves 1 place to the RIGHT. × 100 moves it 2 places and × 1,000 moves it 3 places (count the zeros; 10² = 100 and 10³ = 1,000). Fill empty places with zeros: 3.4 × 100 = 340.

💡 Each small square is 0.01, so 0.69 is 69 squares and 0.21 is 21 squares. 69 + 21 = 90, so you shade 90 squares in all.
✓ Correct!
Not quite. The answer is
💡 Each small square is 0.01, so 0.69 is 69 squares and 0.21 is 21 squares. 69 + 21 = 90, so you shade 90 squares in all.
💡 How to solve: Adding Decimals with Hundredths Grids
Each grid is one whole, each column is one tenth (0.1) and each small square is one hundredth (0.01). To find 1.46 + 0.78, shade 1 whole grid and 46 squares of a second grid in one color. Then shade 78 more squares in a second color, starting right after the first number; when a grid fills up, keep going on the next grid. Count all the shaded squares: 2.24. Check with the standard algorithm: line up the decimal points and add like whole numbers, regrouping when a place goes past 9.

💡 Write each with 2 decimal places so they line up: 5.10, 5.86, 5.36. Compare the whole numbers first, then the tenths and hundredths. From least to greatest: 5.1, 5.36, 5.86.
✓ Correct!

💡 How to solve: Comparing & Ordering Decimals
Line the numbers up by their decimal points and compare place by place from the left: whole numbers first, then tenths, hundredths, and thousandths. Writing zeros at the end (0.4 = 0.400) does not change a decimal and makes the digits easier to compare.

💡 Multiply as whole numbers: 47 × 3 = 141. 4.7 has 1 decimal place and 0.3 has 1 decimal place, so the product has 2: 1.41.
✓ Correct!

💡 How to solve: Multiplying Decimals: 1 Decimal Place × 1 Decimal Place
Line the numbers up on the right and multiply as whole numbers (2.4 × 3.6 → 24 × 36 = 864). Each factor has 1 decimal place, so the answer has 1 + 1 = 2: 8.64.

| 9 | 59.4 |
Not quite. The answer is
💡 Divide as whole numbers: 594 ÷ 9 = 66. 59.4 has 1 decimal place, so the quotient does too: 6.6.
✓ Correct!
Not quite. The answer is
💡 Divide as whole numbers: 594 ÷ 9 = 66. 59.4 has 1 decimal place, so the quotient does too: 6.6.
💡 How to solve: Dividing Decimals by Whole Numbers
Divide as with whole numbers, but first put a decimal point in the quotient directly above the one in the dividend. 8.46 ÷ 3: 8 ÷ 3 = 2 r 2, bring down 4 → 24 ÷ 3 = 8, bring down 6 → 6 ÷ 3 = 2, so 2.82. If there is still a remainder at the end, write a 0 at the end of the dividend (3.4 = 3.40) and keep dividing: 3.4 ÷ 4 = 0.85. Check by multiplying: 0.85 × 4 = 3.4.

Not quite. The answer is
💡 Shade 92 squares for 0.92, then cross out 12 of them for 0.12: 92 − 12 = 80 squares are left. Each square is 0.01, so that is 80 hundredths, or 0.8. Check with the standard algorithm: Line up the decimal points, then work place by place from the right. Hundredths: 2 − 2 = 0. Tenths: 9 − 1 = 8. So 0.92 − 0.12 = 0.80, which is the same as 0.8.

💡 How to solve: Subtracting Decimals with Hundredths Grids
Each grid is one whole, each column is one tenth (0.1) and each small square is one hundredth (0.01). To find 2.16 − 0.37, shade 2 whole grids and 16 squares of a third grid. Then cross out 37 shaded squares, starting from the last ones shaded. Count the shaded squares that are not crossed out: 1.79. Check with the standard algorithm: line up the decimal points and subtract like whole numbers, regrouping when you need to.

💡 19.5 is between 19 and 20. To round to the nearest whole number, look at the tenths digit: 5. 5 is 5 or more, so round up. The ones digit is 9, so it becomes 0 and 1 is added to the tens place. So 19.5 rounded to the nearest whole number is 20.
✓ Correct!

💡 How to solve: Rounding Decimals
Find the digit in the place you are rounding to, then look at the digit just to its right. If that digit is 5 or more, add 1 to the rounding digit; if it is 4 or less, leave it alone. Then drop every digit after the rounding place. If the rounding digit is a 9 and goes up, it becomes 0 and the place to its left goes up by 1 (4.96 to the nearest tenth is 5.0).

💡 How to solve: Multiplying & Dividing Decimals (Mixed Review)
To multiply, ignore the decimal point and multiply like whole numbers, then put back as many decimal places as the decimal factor had. To divide a decimal by a whole number, divide as usual and place the decimal point in the answer directly above the one in the dividend.

💡 The 9 in the tenths place is worth 0.9 and the 9 in the hundredths place is worth 0.09. Each place is worth 10 times the place to its right, and 0.09 × 10 = 0.9. So 0.09 is 110 of 0.9. The answer is 110.
✓ Correct!
Not quite. The answer is
💡 The 9 in the tenths place is worth 0.9 and the 9 in the hundredths place is worth 0.09. Each place is worth 10 times the place to its right, and 0.09 × 10 = 0.9. So 0.09 is 110 of 0.9. The answer is 110.
💡 How to solve: Decimal Place Value to Thousandths
After the decimal point come the tenths, hundredths, and thousandths places. Each place is 10 times the place to its right and 110 of the place to its left. To write a number in standard form, put each digit in its place and write 0 in any empty place.
