Questions for calculating perimeters and areas of shapes.

 Basics, percentage of an amount, converting to fractions and decimals.

Students seem to miss the fact that division is actually multiplication by the reciprocal or the inverse of multiplication. This question attempts to address that.

Fractions already have a common denominator. Addition and subtraction 50:50 split, when subtracting, the answer is negative half the time. Students shouldn't have to worry about reducing fractions by design.

Fractions don't have a common denominator. Need to find one. Addition and subtraction 50:50 split.

Students seem to not realise that $\frac{a}{b}\times c=c\times\frac{a}{b}=\frac{a\times c}{b}=\frac{c\times a}{b}=a\times c \div b=a\div b\times c=c\div b \times a \ne c \div (b\times a)\ldots $ etc. This question is my attempt to help rectify this.

The dimensions of a rectangle are given in m and cm. Compute the area or perimeter.

Useful for a review of the base 10 number system before introducing different bases and also just ensuring students understand how the base 10 system works.

old question, way too many things in one question! I have made better questions out of each part now.

Nice easy case except divisor is a double digit. There is no remainder. 

Divisor is a two digit number. There is a remainder which we express as a decimal by continuing the division process. No rounding is required by design (another question will include rounding off).

Divisor is a two-digit number. There is a remainder which we express as a decimal by continuing the division process. Rounding is required to one decimal place. The working suggests determining the second decimal place so the student knows whether to round up or down.

Divisor is double digit. There is a remainder which we express as a fraction. 

The simplest case. Divisor is single digit. There is no remainder.

Subtracting a decimal with 3 decimal places from a decimal with 2 or 3 decimal places. borrowing is necessary. This was modified from a subtraction question using integers with each number divided by 1000 so the variables have names referring to ones, tens, hundreds etc.

I think I prefer the other question I made called "Rounding to 0, 1, 2 and 3 decimal places"
