Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Write each of the following as a whole number or decimal:

i) $\var{num1} \times 10^\var{po[0]}$

Gap 0.

ii) $\var{num2} \times 10^\var{po1}$

Gap 1.

iii) $\var{num3[0]} \times 10^\var{po[2]}$

Gap 2.

iv) $\var{num4} \times 10^\var{po2}$

Gap 3.

v) $\var{num3[1]} \times 10^\var{po[4]}$

Gap 4.

Advice

Part 1

Move the decimal point "the power number" of times to the right for positive power and to the left for negative power:

$\var{num1} \times 10^\var{po[0]} = \var{ans1}$ (move the decimal point $\var{po[0]}$ places to the $\var{advicedir0}$ )

$\var{num2} \times 10^\var{po1} = \var{ans2}$ (move the decimal point $\var{po[1]}$ places to the $\var{advicedir1}$ )

Part 2

Count the number of times the decimal point has to be moved to get only one number to the left of the decimal point, this count becomes the power on the $\times 10$ .

If the decimal point is moved to the left the power number is positive and if it is moved to the right the power is negative:

$\var{a11} = \var{num21[0]} \times 10^\var{pow[0]}$
