💡 How to solve: Place Value & Rounding (Mixed Review)
Name the places from right to left: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions. To round, look at the digit just to the right of the rounding place: 5 or more rounds up, 4 or less stays the same. Then change the digits after it to zeros.

💡 How to solve: Subtracting Across Zeros
When the digit you need to borrow from is 0, keep moving left until you reach a digit that is not 0. Borrow 1 from it, and every 0 you passed becomes 9; the column you started in gets 10 more. Example: 5,003 − 1,876. The ones need to borrow, but the tens and hundreds are 0. Borrow from the 5 thousands: 5,003 becomes 4 thousands, 9 hundreds, 9 tens and 13 ones. Now subtract: 13 − 6 = 7, 9 − 7 = 2, 9 − 8 = 1, 4 − 1 = 3. So 5,003 − 1,876 = 3,127. A quick trick: 5,003 − 1,876 is the same as 5,002 − 1,875 (take 1 from both), and that needs no borrowing across zeros.

💡 How to solve: Geometry: Lines & Symmetry
Perpendicular lines meet to make a right angle (90°). Parallel lines never meet and stay the same distance apart. A line of symmetry folds a shape into two matching halves, so count every way you could fold it.

💡 How to solve: Add & Subtract Fractions with Like Denominators (Mixed Review)
When the denominators are the same, add or subtract only the numerators and keep the denominator: 38 + 28 = 58. If the numerator becomes bigger than the denominator, change it to a mixed number: 75 = 1 25.

💡 How to solve: Multiplying by 10, 100 & 1,000
Multiplying by 10 moves every digit one place to the left, so a 0 fills the ones place: 47 × 10 = 470. Multiplying by 100 adds two zeros (47 × 100 = 4,700) and by 1,000 adds three zeros (47 × 1,000 = 47,000). Zeros already in the number stay: 450 × 100 = 45,000 and 305 × 10 = 3,050. For a missing factor, count how many zeros were added: 36 × ___ = 36,000 needs 1,000.

💡 How to solve: Simplifying Fractions to Lowest Terms
Find the greatest common factor (GCF) of the numerator and the denominator, then divide both by it. Example: 1236. The GCF of 12 and 36 is 12, so 12 ÷ 12 = 1 and 36 ÷ 12 = 3: 1236 = 13. You can also divide by a smaller common factor again and again until only 1 divides both (1236 → 618 → 26 → 13). For an improper fraction, simplify and write it as a mixed number: 184 = 92 = 4 12.

💡 How to solve: Multiplicative Comparison ("Times as Many")
"Times as many" means multiply: 4 times as many as 6 is 4 × 6 = 24. To find the smaller amount, divide the larger amount by how many times: 24 ÷ 4 = 6. To find how many times as many, divide the larger amount by the smaller one.

💡 How to solve: Points, Lines, Line Segments & Rays
A point is an exact location. A line goes on forever in both directions (arrows on both ends). A line segment has two endpoints. A ray has one endpoint and goes on forever in one direction. Two rays with the same endpoint make an angle. Parallel lines never meet; perpendicular lines meet at a right angle.

💡 How to solve: Adding Decimals with Bar Charts
Read the number at the top of each bar to find its value. To add decimals, line up the decimal points and add each place from right to left, just like whole numbers. For example, if the chart shows Mon = 1.4 km and Tue = 2.3 km, add: 1.4 + 2.3 = 3.7 km.

💡 How to solve: Classify Triangles by Angles & Sides
By angles: a right triangle has one 90° angle, an obtuse triangle has one angle greater than 90°, and an acute triangle has all three angles less than 90°. By sides: equilateral means all three sides are equal, isosceles means exactly two sides are equal, and scalene means no sides are equal.

💡 How to solve: Multiplying & Dividing by 10, 100 & 1,000 (Mixed Review)
Multiplying by 10 moves every digit one place to the left, so a zero fills the ones place: 37 × 10 = 370, 37 × 100 = 3,700 and 37 × 1,000 = 37,000. Dividing by 10, 100 or 1,000 moves the digits back to the right: 4,500 ÷ 100 = 45. For multiples of 10, multiply the basic fact, then put the zeros back: 30 × 400 is 3 × 4 = 12 with three zeros, 12,000. To divide, take the same number of zeros off both numbers first: 2,400 ÷ 60 = 240 ÷ 6 = 40.

💡 How to solve: Subtracting Fractions with Like Denominators
When the denominators are the same, subtract the numerators and keep the denominator: 56 − 26 = 36. Then simplify: 36 = 12. If the answer is more than 1, write a mixed number: 114 − 24 = 94 = 2 14. To take a fraction from a whole number, write the whole number as a fraction with the same denominator: 2 − 38 = 168 − 38 = 138 = 1 58.

💡 How to solve: Dividing by 10, 100 & 1,000
Dividing by 10 moves every digit one place to the right, so one 0 comes off the end: 340 ÷ 10 = 34. Dividing by 100 takes off two zeros (5,600 ÷ 100 = 56) and by 1,000 takes off three zeros (42,000 ÷ 1,000 = 42). Only take off the zeros at the end that match: 45,000 ÷ 100 = 450 and 30,500 ÷ 10 = 3,050. For a missing number, count the zeros: 4,700 ÷ ___ = 47 needs 100.

💡 How to solve: Subtracting Decimals Using Expanded Form on a Number Line
Write the number you are taking away in expanded form, then take away one part at a time on the number line. Example: 2.7 − 1.4. In expanded form 1.4 = 1 + 0.4. Start at 2.7, jump back 1 to land on 1.7, then jump back 0.4 to land on 1.3. So 2.7 − 1.4 = 1.3. With hundredths there can be three jumps: 3.85 − 1.32 → 1.32 = 1 + 0.3 + 0.02, so 3.85 → 2.85 → 2.55 → 2.53. If a jump passes a whole number, keep counting back past it: 4.2 − 0.7 → 4.2 back 0.2 is 4.0, then 0.5 more is 3.5.

💡 How to solve: Subtracting Decimals (Tenths & Hundredths)
Line up the decimal points, then subtract from the right just like whole numbers, borrowing when the top digit is smaller. Put the decimal point in the answer straight below the others. Example: 6.42 − 2.75: 2 is less than 5, so borrow: 12 − 5 = 7; 3 is less than 7, so borrow again: 13 − 7 = 6; 5 − 2 = 3. The difference is 3.67. If the places are different, write zeros to fill the gaps: 5.6 − 2.38 = 5.60 − 2.38 = 3.22, and 5 − 2.37 = 5.00 − 2.37 = 2.63.
