What's the difference between a prime number and a composite number?
A prime number only has 1 and itself as factors. 17 is an example of a prime number because only 1X17=17. A composite factor has more factors than 1 and itself. 12 is a composite number because 1x12=12, but so does 2x6 and 3x4.
What's the difference between past tense and a past participle.
We use the past tense to show something had happened at one point in the past. For example: Bobby picked his nose yesterday. We use the past participle form of a verb to show something that started in the past but continues to the present. A past participle contains the main verb plus the helping verb have/has/had. For example: Bobby has picked his nose since first grade.
What type of teacher is the most effective?
The most effective teachers are warm demanders. They care about their students as individuals, but they have high expectations for their students. They convey those expectations through respectful feedback.
