1st or 2nd grade
The average ages for grades K - 12 are between 5 and 18. Kindergarten is 5 and 6 year olds. 1st grade is 6 and 7 year olds. 2nd grade is 7 and 8 year olds. 3rd grade is 8 and 9 year olds. 4th grade is 9 and 10 year olds. 5th grade is 10 and 11 year olds. 6th grade is 11 and 12 year olds. 7th grade is 12 and 13 year olds. 8th grade is 13 and 14 year olds. 9th grade is 14 and 15 year olds. 10th grade is 15 and 16 year olds. 11th grade is 16 and 17 year olds. And 12th grade is 17 and 18 year olds. This only works for the average student that hasn't been held back at all at any grades.
it means like that 3rd grade isi for 5-7 year olds
7th grade is actually equivalent to Year 8 in England. In England, children attend "Reception" from age 4-5, and then they start labeling them as "years" the next year, so 5-6 year olds attend Year 1. But in America, we have Pre-K for ages 4-5, and then kindergarten for 5-6 year olds, and then 1st grade for 6-7 year olds. So that's how we end up being behind England in the year numbers.
depends on how good the 15 year old is at playing the piano
Year 10 in England is equivalent to 9th grade in America. We are always a number behind. Because in England, I know it starts with Reception (ages 4-5), then Year 1 (ages 5-6), Year 2 (ages 6-7), and so on. In America, we call it pre-kindergarten or "pre-K" for 4-5 year olds, and then kindergarten for 5-6 year olds. So we don't start numbering the years until the next year...we start with 1st grade (ages 6-7) and 2nd grade (7-8) and so on.
No.
not two year olds they have to be like 7
Justin likes 7 year olds as friends or fans, but certainly not like a girlfriend.
. . . don't 10 and 7 year olds still think the other gender has cooties? And isn't 7 a little young to be dating?
Let's call the number of 4-year-olds "x" and the number of 5-year-olds "y". From the problem, we know that: x + y = 63 (because there are a total of 63 students) x = y + 7 (because there are 7 more 4-year-olds than 5-year-olds) We can use substitution to solve for one of the variables. From the second equation, we know that y = x - 7. We can substitute this into the first equation: x + (x - 7) = 63 Simplifying: 2x - 7 = 63 Adding 7 to both sides: 2x = 70 Dividing both sides by 2: x = 35 So there are 35 4-year-olds in the preschool.
