Study Notes
Problem Solving Strategies
- To check an answer, an equation can be used to verify the calculation, for example, dividing 765 by 5 to find the number of boxes needed.
Unit Conversions
- A small bag of birdseed has a mass of 2 kilograms, and a large bag has three times as many kilograms, so the combined mass can be calculated by converting both to grams.
- 1 kilogram is equal to 1,000 grams.
Prime Numbers
- A prime number is a number that is only divisible by 1 and itself.
- Both 11 and 29 are prime numbers.
Measurement
- To find the length of a wooden board after cutting off a certain length, the original length and the length cut off can be subtracted.
- The length of the remaining board can be calculated using subtraction, for example, 11 inches - 4 inches = 7 inches.
Equations
- An equation can be used to represent a situation, for example, 239 ÷ 4 = 5 × 7 + 35.
- The equation can be solved to find the unknown value.
Tables and Graphs
- A table can be used to show the relationship between the number of boxes and the number of crayons.
- The table can be used to calculate the number of crayons in a certain number of boxes, for example, 132 boxes.
Perimeter and Area
- The perimeter of a rectangle can be calculated using the formula: perimeter = 2 × (length + width).
- The length and width of a rectangle can be calculated using the perimeter and the formula.
Fractions
- A fraction can be represented as a shaded part of a grid model.
- The fraction can be compared to another decimal, for example, 0.67 is greater than 0.6.
Word Problems
- A word problem can be solved using an equation, for example, finding the number of trees that can be planted with a budget of $936.
- The equation can be used to find the unknown value, for example, the number of trees that can be planted.
