This page introduces fundamental concepts of percentages and basic equation solving.
Key points covered:
Example: To find 54% of 750, first calculate 1% (750 ÷ 100 = 7.5), then multiply by 54 to get 405.
Highlight: The page emphasizes the importance of understanding the relationship between percentages and decimals for efficient calculations.
This final page introduces the concept of volume and its measurement.
Key points covered:
Definition: Volume is a measurement of the amount of space inside a 3D object.
Highlight: The page suggests that there are quicker ways to calculate volume than counting individual cubes, hinting at formulas to be learned in future lessons.
The page sets the foundation for more advanced volume calculations in future mathematics studies.
This page delves deeper into perimeter calculations and provides additional practice with various types of equations.
Key points covered:
Definition: Perimeter is the total length around the edge of a shape.
Example: For a rectangle with length 6cm and width 4cm, the perimeter can be calculated as 2(6cm + 4cm) = 20cm.
The page also includes a word problem about Noah's number, encouraging students to apply their equation-solving skills in a different context.
This page focuses on applying equation-solving skills to real-world scenarios and word problems.
Key concepts covered:
Example: A problem about upgrading airline seats is presented, where students must form and solve an equation to find the cost of a standard seat.
Highlight: The page stresses the importance of carefully reading word problems and identifying the key information needed to form equations.
This page introduces more complex multi-step equations and the balancing method for solving them.
Key points covered:
Vocabulary: The balancing method involves performing the same operation on both sides of an equation to maintain equality while isolating the variable.
Example: For the equation 7x + 4 = 25, first subtract 4 from both sides, then divide by 7 to get x = 3.
The page emphasizes the importance of working systematically and using inverse operations in the correct order to solve multi-step equations.
This page focuses on solving one-step equations using inverse operations, a fundamental skill in algebra.
Key concepts covered:
Definition: Inverse operations are mathematical operations that undo each other, such as addition and subtraction or multiplication and division.
Example: For the equation x + 6 = 8, subtract 6 from both sides to isolate x: x = 8 - 6 = 2.
The page provides clear explanations and multiple examples to reinforce the concept of using inverse operations to solve equations.
This page introduces parallelograms and explains how to calculate their areas.
Key concepts covered:
Vocabulary: A parallelogram is any quadrilateral with two pairs of parallel sides.
Highlight: The area of a parallelogram is calculated using the same formula as a rectangle: area = base × height.
The page emphasizes the importance of using the perpendicular height, not the slant height, when calculating the area of a parallelogram.
