• Question

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.

• Question

This question is to test if you know how to use your calculator correctly.

Question

• Question

Some students believe a decimal is larger if it is longer, some believe a decimal is larger if its first non-zero digit is larger.

• Question

• Question

Converting between giga, mega, kilo, base, milli and micro, nano. Metres, grams and litres.

• Question

I feel this question has too many questions inside it, I have since made a question that just asks a single division problem called Decimals: Division (includes rounding the answer).

• Question

a) Multiplying decimals with a single non-zero digit. Students are told to preserve the number of decimal places (from the question to the answer).

b) Multiplying decimals requiring the multiplication algorithm.

• Question

By powers of ten I mean a 1 followed by some 0s. The scientific notation questions will take care of the power of ten notation.

• Question

Issues: alignment in columns in the working - not sure what to do about it

Decimal divided by a decimal. Multiply by a power of ten to get an integer divisor. Long division process. There is a remainder which we express as a decimal by continuing the long division process. Rounding is required to some number of decimal places.

• Question

Divisor is a double digit. There is a remainder which we express as a decimal by continuing the long 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.

• Question

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

• Decimals: rounding
Question

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

• Question

Round random numbers to the closest whole number, 1 to 3 decimals places. Also rounding that could show common misunderstandings.

• Question

Divisor is single digit. There is a remainder which we express as a decimal by continuing the long 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.

• Question

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

• Question

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

• Question

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

• Question

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

• Question

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

• Question

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

• Question
