Front

What is line symmetry?

Back

Line symmetry, also known as reflection symmetry, occurs when a figure can be divided into two identical halves that are mirror images of each other along a line.

Front

How many lines of symmetry does the letter 'I' have?

Back

The letter 'I' has 2 lines of symmetry: one vertical and one horizontal.

Front

What is the formula for calculating the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

If each small square has an area of 36 square units, how do you find the total area of a shaded region made up of these squares?

Back

To find the total area of the shaded region, count the number of small squares that are shaded and multiply by the area of each square (36 square units).

Front

How do you determine the number of cups of blueberries needed for a recipe that calls for 1 cup per dozen muffins?

Back

To determine the number of cups needed, divide the total number of muffins by 12 (the number of muffins per dozen) and multiply by 1 cup.

Front

What is the sum of an arithmetic sequence?

Back

The sum of an arithmetic sequence can be calculated using the formula: Sum = (number of terms / 2) × (first term + last term).

Front

How do you find missing numbers in a number pattern?

Back

To find missing numbers in a number pattern, identify the rule or pattern (e.g., addition, subtraction) and apply it to fill in the blanks.

Front

What is the total number of trees if a farmer has three woods with 437, 391, and 267 trees respectively?

Back

To find the total number of trees, add the number of trees in each wood: 437 + 391 + 267 = 1095 trees.

Front

What is the concept of area in geometry?

Back

Area is the measure of the amount of space inside a two-dimensional shape, typically measured in square units.

Front

How do you calculate the area of a shaded region made up of multiple squares?

Back

To calculate the area of a shaded region made up of multiple squares, count the number of shaded squares and multiply by the area of one square.
