Introduction to Mixed Operations – Understanding mixed operations – Combining addition, subtraction, multiplication, and division – Daily life applications – Examples: budgeting, cooking, and shopping – Correct order of operations – Use PEMDAS to solve problems correctly – Practice with word problems | This slide introduces students to the concept of mixed operations with whole numbers, which is a combination of addition, subtraction, multiplication, and division. Emphasize real-life applications such as managing a budget, following a recipe, or calculating total costs while shopping to make the concept relatable. Highlight the importance of following the correct order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), to ensure accurate results. Encourage students to solve word problems using these operations to reinforce their understanding. Provide examples and guide them through the process of identifying the operations required to solve each problem.

Addition and Subtraction with Word Problems – Review addition & subtraction – Learn key operation terms – ‘Sum’ and ‘Total’ mean add; ‘Minus’ and ‘Difference’ mean subtract – Solve real-world problems – Use clues in the question to decide if you add or subtract – Practice with an example – If you start with 5 apples and get 3 more, you add: 5 + 3 = 8 apples | Begin with a quick review of how to add and subtract whole numbers, ensuring students are comfortable with the operations. Introduce key terms like ‘sum,’ ‘difference,’ ‘total,’ ‘minus,’ and ‘plus,’ which signal what operation to use in word problems. Work through an example together, such as the apple problem provided, to demonstrate how to translate a word problem into a math equation. Encourage students to identify keywords and phrases that help determine the correct operation. Provide additional practice problems for students to apply these concepts independently.

Multiplication and Division Mastery – Reviewing multiplication/division – Understanding ‘Product’ and ‘Quotient’ – ‘Product’ means the result of multiplication, ‘Quotient’ is the result of division – ‘Times’ and ‘Divided by’ terms – ‘Times’ indicates multiplication, ‘Divided by’ indicates division – Solve a sticker pack problem – If 1 pack has 6 stickers, 4 packs have 4 times 6, which equals 24 stickers | Begin with a quick review of multiplication and division to refresh the students’ memory. Introduce the key terms ‘Product’ and ‘Quotient’, ensuring that students understand these are the results of multiplication and division, respectively. Clarify the usage of ‘Times’ as a multiplication indicator and ‘Divided by’ for division. Work through the example problem by visualizing the packs of stickers and using multiplication to find the total number of stickers. Encourage students to visualize problems and to use these terms when describing their mathematical processes. This will help solidify their understanding and ability to solve word problems involving multiplication and division.

Word Problems: Addition and Subtraction – Read and understand the problem – Grasp the story and what’s being asked. – Decide: add or subtract? – Look for keywords like ‘total’ or ‘left’ to choose the operation. – Solve with step-by-step example – Example: If Lisa has 10 apples and buys 5 more, how many does she have now? – Practice with class activity – We’ll solve different word problems together in class. | This slide introduces students to the process of solving addition and subtraction word problems. Start by reading the problem carefully and understanding the scenario. Teach students to identify keywords that signal which operation to use, such as ‘in all’ for addition or ‘remain’ for subtraction. Walk through an example problem as a class, demonstrating how to break it down into steps and solve it. Finally, engage the students with a class activity where they solve similar problems in groups or pairs, encouraging collaboration and discussion. Provide guidance and support as they work through the problems.

Multiplication & Division in Word Problems – Understand multiplication & division – Multiplication combines equal groups, division splits into equal parts – Deciding to multiply or divide – Multiply to find total items in groups, divide to find number in each group or number of groups – Step-by-step problem-solving – Break down the problem, identify keywords, and choose the operation – Example: Multiplication & division – If 4 bags have 6 apples each, how many apples in total? (Multiply: 4*6) | This slide aims to help students grasp the concepts of multiplication and division within the context of word problems. Begin by explaining that multiplication is used when combining equal groups, while division is used when separating into equal parts. Emphasize the importance of identifying keywords in word problems that hint at which operation to use. Walk through a step-by-step approach to solving a problem, including reading the problem carefully, identifying what is being asked, and choosing the correct operation. Use an example problem to illustrate the process, such as determining the total number of apples in multiple bags. Encourage students to practice with a variety of problems to become comfortable with choosing the appropriate operation.

Understanding Order of Operations – What is order of operations? – It’s the sequence used to solve math problems – Learn PEMDAS rule – PEMDAS: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction – Apply PEMDAS to 3 + 5 x 2 – First multiply 5 x 2, then add 3 – Practice with more examples | The slide introduces the concept of the order of operations, which is crucial for solving math problems correctly. PEMDAS is an acronym that helps students remember the sequence: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Use the example 3 + 5 x 2 to illustrate the importance of following this order, emphasizing that multiplication comes before addition. After solving the example, encourage students to practice with additional problems to reinforce the concept. Provide a variety of exercises with different operations to ensure students understand how to apply PEMDAS in various situations.

Mixed Operation Word Problems – Combine operations in one problem – Read to determine the steps – Example: addition, subtraction, multiplication – If Sarah has 15 apples, gives away 5, then buys 3 times more, how many does she have? – Solve step by step – First subtract, then multiply the result | This slide introduces students to the concept of mixed operation word problems, which require the use of more than one arithmetic operation (addition, subtraction, multiplication, division) to solve. Emphasize the importance of reading the problem carefully to understand what is being asked and to determine the order of operations. Use the example problem to illustrate how to break down a problem into manageable steps, solve each part in the correct sequence, and combine the results to find the final answer. Encourage students to practice with similar problems and to always check their work for accuracy.

Class Activity: Solve the Mystery with Math – Pair up for a math mystery – Receive a unique mystery problem – Use mixed operations to find clues – Combine addition, subtraction, multiplication, and division to solve – Present your solution to the class – Explain how you used math to solve the mystery | This activity is designed to encourage collaborative problem-solving and application of mixed mathematical operations in a fun and engaging way. Each pair of students will receive a word problem that serves as a ‘mystery’ to be solved using a combination of addition, subtraction, multiplication, and division. The problems should be crafted to require the use of at least two different operations. After solving their mystery, students will present their solution and the reasoning behind their approach to the entire class. This will not only reinforce their understanding of the concepts but also enhance their communication and reasoning skills. For the teacher: Prepare diverse problems of varying difficulty to cater to different skill levels within the class. Ensure that the mysteries are contextually engaging and require logical reasoning. Have a list of guiding questions ready to prompt students if they get stuck.
