When faced with a math problem, the first step is to carefully read and understand the problem. Identify what the problem is asking for and what information is given.

After understanding the problem, plan out a solution. Determine which mathematical operations or strategies are needed to solve the problem. Think about what formulas or concepts may be relevant to the problem.

Once you have a plan, begin solving the problem step by step. Show all your work neatly and clearly, so that you can easily trace back your steps if needed.

After solving the problem, review your solution and make sure it makes sense. Check your work for any errors and ensure that you have answered the question that was asked.

Here are some sample math problems to practice:

- Alice has 3 apples and she gives 1 to her friend. How many apples does Alice have now?
- If a book has 250 pages and John reads 30 pages per day, how many days will it take for him to finish the book?
- The perimeter of a rectangle is 30 cm and its length is 10 cm. What is the width of the rectangle?

- To find out how many apples Alice has now, we will subtract 1 from 3. Alice has 2 apples left.
- To find out how many days John will take to finish the book, we will divide the total number of pages (250) by the number of pages he reads per day (30). It will take John 8.33 days to finish the book.
- To find the width of the rectangle, we can use the formula for the perimeter of a rectangle: 2(length + width) = 30. Given the length (10), we can substitute it into the formula and solve for the width. The width of the rectangle is 5 cm.

For further practice, try solving more math problems from textbooks, online resources, or math problem-solving websites. The more you practice, the more confident you will become in solving various types of math problems.

Grade 7 Curriculum Focal Points (NCTM)

Number and Operations and Algebra: Developing an understanding of operations on all rational numbers and solving linear equations

Students extend understandings of addition, subtraction, multiplication, and division, together with their properties, to all rational numbers, including negative integers. By applying properties of arithmetic and considering negative numbers in everyday contexts (e.g., situations of owing money or measuring elevations above and below sea level), students explain why the rules for adding, subtracting, multiplying, and dividing with negative numbers make sense. They use the arithmetic of rational numbers as they formulate and solve linear equations in one variable and use these equations to solve problems. Students make strategic choices of procedures to solve linear equations in one variable and implement them efficiently, understanding that when they use the properties of equality to express an equation in a new way, solutions that they obtain for the new equation also solve the original equation.
