# Parallel Lines

## Lines are parallel if they are always the same distance apart (called “equidistant”), and will never meet. Just remember:

### Always the same distance apart and never touching.

The red line is parallel to the blue line in both these cases:

# Type of angle

Type of Angle Description Acute Angle an angle that is less than 90° Right Angle an angle that is 90° exactly Obtuse Angle an angle that is greater than 90° but less than 180° Straight Angle an angle that is 180° exactly Reflex Angle an angle that is greater than 180°

# Teach fractions Today, let’s have a look at how to read and pronounce fractions in English. Outside of the math class and in the real world fractions are useful for buying things and talking about distance. So let’s begin! Basically, we use cardinal numbers (like 1, 2, 3, 4) to read the figure on the top of the fraction, and ordinal numbers (like third, fourth, fifth) to read the figure on the bottom of the fraction. When we write the fraction in words, we use a hyphen between the cardinal number and the ordinal number. Here are some examples:

• We pronounce 1/3 as one-third, 1/4 as one-fourth, and 1/8 as one-eighth.

As well, “a” means “one” so:

• We pronounce 1/3 as a third, 1/4 as a fourth, and 1/8 as an eighth (written without the hyphen.)

In English grammar, ordinal numbers are countable, so you need to add “s” to the word:

• We pronounce 2/3 as two-thirds, 3/4 as three-fourths, and 6/8 as six-eighths.

We have special words to talk about fractions that have “2” and “4” on the bottom:

• We pronounce 1/2 as one-half, 1/4 as one-quarter, and 3/4 as three-quarters.

# 20 Tips for Helping Children Become Good Problem Solvers

Solving problems, especially word problems, are always a challenge. To become a good problem solver you need to have a plan or method which is easy to follow to determine what needs to be solved. Then the plan is carried out to solve the problem. The key is to have a plan which works in any math problem solving situation. For students having problems with problem solving, the following 20 tips are provided for helping children become good problem solvers.

Tip 1: When given a problem to solve look for clues to determine what math operation is needed to solve the problem, for example addition, subtraction, etc.

Tip 2: Read the problem carefully as you look for clues and important information. Write down the clues, underline, or highlight the clues.

Tip 3: Look for key words like sum, difference, product, perimeter, area, etc. They will lead you to what operation you need to use. Rewrite the problem if necessary.

Tip 4: Look for what you need to find out, for example: how many will you have left, the total will be, everyone gets red, everyone gets one of each, etc. They will also lead you to the type of operation needed to solve the problem.

Tip 5: Use variable symbols, such as “X” for missing information.

Tip 6: Eliminate all non-essential information by drawing a line through this distracting information.

Tip 7: Addition problems use words like sum, total, in all, and perimeter.

Tip 8: Subtraction problems use words like difference, how much more, and exceeds.

Tip 9: Multiplication problems use words like product, total, area, and times.

Tip 10: Division problems use words like share, distribute, quotient, and average.

Tip 11: Draw sketches, drawings, and models to see the problem.

Tip 12: Use guess and check techniques to see if you are on the right track. Continue reading 20 Tips for Helping Children Become Good Problem Solvers
