In other words, they never memorized their multiplication tables! Many times I have seen a student do poorly due to a weakness in basic math facts they should have learned in third grade.
They're also available for nearly all grade levels. There are printable middle school, high school, elementary school, and even pre-school worksheets.
When a child learns to relate math to everyday questions, he will be great at it from the simplest addition all the way to trigonometry. To convert percentages, decimals and fractions is thus one essential skill.
Review subtraction of 2 numbers whose sums would be 18 or less.
Subtract 1- or 2-digit number from a 2-digit number with/without renaming.
As a middle-school math teacher, I have seen many students who do understand abstract concepts, and even enjoy learning about things like Pi and the Pythagorean Theorem, but who appear to be unable to do so due to a weak grasp of math fundamentals.
