Mixing Maths Problems Can Teach You Which Method to Choose
A worksheet grouped by type gives you a clue that an exam may not provide. Carefully mixed practice removes that clue.
The first ten questions all use the same formula. After the first example, choosing the method is easy because the worksheet has already chosen it for you.
Separate solving from selecting
The Learning Scientists describe interleaving as mixing topics or problem types during practice. An original maths exercise might combine a few question types you have already studied, then ask you to name the method before calculating.

For each question, write one sentence explaining the choice. What feature tells you which approach fits? That sentence is useful even when the arithmetic later goes wrong, because it separates a selection error from a calculation error.
Use comparison, not chaos
Mixing should have a purpose. Throwing in unrelated material at random can make the session confusing without teaching the distinction you need. Start with a manageable set and check answers carefully.
If a method is entirely new, you may need clearer instruction and initial focused practice before using it in a mixed set. The aim is not to make learning feel difficult for its own sake. It is to practise a real part of problem-solving: recognising the kind of question in front of you when nobody has labelled the next ten answers in advance.
