"Creating excel interactive workbooks is very simple and
uses the 'if' command to provide instant feedback. For example
to convert between grams and kilograms the following could be
used:
=IF(B3=A3*1000,A3=B3/1000)
B3 (in this example) is the cell where the child types the
answer, A3 (in this example) is the cell where the value to be
converted is placed. Excel will automatically put true or
false in the cell where this type of formula is written. The
examples make things a bit clearer. For a closed answer, type
something like:
=IF(D3=400,"Correct")
Where D3 (in this example) is the cell where the answer is
typed and 400 is the answer (in this example).
Such spreadsheets work really well for time or conversion
activities. However, it is worth locking the formula cells to
stop children accidentally changing them. Using a colour fill
gets rid of the gridlines and helps make the sheet look less
'clinical'." |
