Guided Notes
Key concepts students will learn:
- •
When translating word problems into inequalities, keywords such as 'at least' or 'no less than' indicate a greater than or equal to symbol, while 'at most' or 'no more than' indicate a less than or equal to symbol.
- •
The three steps to solving word problems with inequalities are to define a variable, write the inequality, and then solve the inequality.
- •
When a word problem includes a fraction such as '3/10th of a number,' this indicates multiplication by the fraction 3/10.
