Add, subtract, multiply, and divide with decimals; add with negative integers; subtract
positive integers from negative integers; and verify the reasonableness of the results.
Demonstrate proficiency with division, including division with positive decimals and long
division with multidigit divisors.
Lesson to be used by EDI-trained teachers only.
Concept Development
To divide is to separate a number into equal groups.
To divide decimal numbers, the problem must be in long division form.
• To begin long division, the divisor must be a whole number.
• If the divisor is a decimal number, move the decimal point to the
right until it becomes a whole number.
 The decimal point in the dividend will move the same number of places.
