Concepts: - We can find a missing addend by subtracting the known addend from the sum. Example: 12 + m = 31 - solution: 31 – 12 = 19, therefore the m = 19 - We can find a missing minuend (first number in a subtraction problem) by adding the other two numbers. Example: w – 16 = 24 – solution 16 + 24 = 40, therefore w = 40 - We can find a missing subtrahend (second number in a subtraction problem) by subtracting the difference from the minuend. Example: 236 – y = 152 – solution 236 – 156 = 84, therefore y = 84 - We can find a missing factor by dividing the product by the known factor. Example: A x 6 = 72 – solution: 72 ÷ 6 = 12, therefore A = 12 - We can find the missing dividend (the number inside the division box) by multiplying the other two numbers. We can find either the divisor or quotient (the numbers outside the box) by dividing. - When there is more than one addition or subtraction step within a problem, we take the steps in order from left to right. In this problem we first subtract 4 from 9. Then we add 3. 9 – 4 + 3 = 8 - If a different order of steps is desired, parentheses are used to show which step should be taken first. In the problem below, we first add 4 and 3 to get 7. Then we subtract 7 from 9. 9 – (4 + 3) =2Skills: - Ordering mathematical operations - Finding missing numbers in multiplication and division - Finding missing numbers in addition and subtraction. - Using appropriate vocabulary for mathematical arithmetic operations.Attitudes: - Awareness that math is used in our daily life. - Appreciation for numbers. - Respect for others and their ideas. - Cooperation as students work in groups.Teaching/Learning Strategies:Day One - Students perform warm-up activities – Addition Facts, Mental Math, Problem Solving - Present and addition problem to students. - Have them cover one addend and then the next with their fingers. - Discuss with students what steps they would do to find any of the missing addends they covered with their fingers. - Listen to students responses and acknowledge anyone who shows the correct steps. - Model out for children the correct steps to solve these problems. - Allow students to practice and to assess their understanding of it. - Next, present a subtraction problem for students on the white board. - Ask them to cover the subtrahend with their fingers and describe what would they do to find that missing number. - Listen to students how they would go about solving this problem.

JanuaryWeek 16Subject: MathematicsLesson Topics: Least Common Multiple, Reciprocals; Measuring and Drawing Angles with a Protractor;Areas of Rectangle; Expanded Notation, More on Elapsed Time; Writing Percent as Fractions, part 1Previous Knowledge:Students have worked with multiples, and have studies anglesObjectives:Through investigation, cooperative learning, individual work and use of manipulatives, students will be able to: 1. Identify common multiples of two numbers. 2. Find the least common multiple (LCM) OF TWO NUMBERS. 3. Identify reciprocals as numbers that have a product of 1 when multiplied 4. Use a protractor to find the measure of an angle and to draw an angle with the given measurement. 5. Identify square units as the units used to measure area. 6. Multiply length by width to find the area of a rectangle. 7. Find the side length and the perimeter of a square when the area of the square is known. 8. Write a number in expanded notation, 9. Rename hours and minutes as minutes to solve an elapsed-time problem. 10. Write percent as a reduced fraction.Concepts: - When the multiples of two or more numbers are listed in order from least to greatest, the first number that is a common multiple is always the least common multiple (LCM). - Least common multiple (LCM) – The smallest whole number that is a multiple of two or more given numbers. - Reciprocal – two numbers whose product is 1. - Protractor – is a tool used to measure and draw angles. - To ensure that the correct scale on the protractor is used, it helps to decide whether an angle is acute, obtuse, or right before measuring. - Area is the number of square units needed to cover a surface. - Formula for finding area of a rectangle = Length x Width - To write a number in expanded notation, each nonzero digit is written times its place value. Example: (3 x 1000) + (9 x 100) + (4 x 10) - The hours of the day are divided into two parts: a.m. and p.m. We can use the later-earlier difference pattern to solve elapsed-time problems about hours and minutes. - A percent is actually a fraction with a denominator of 100. The word percent and its symbol %, mean “per hundred.” To write a percent, we remove the percent sign and write the number as the numerator and 100 as the denominator.

- A percent is actually a fraction with a denominator of 100. The word percent and its symbol %, mean “per hundred.” To write a percent, we remove the percent sign and write the number as the numerator and 100 as the denominator. - Each place to the right of the ones place has a value that is one tenth of the value of the place to its left. - Decimal numbers are actually fractions of denominators 10, 100, 1000 and so on. The denominator of decimal is not written. Instead, the denominator is indicated by the number of decimal place values. - To subtract a mixed number from a whole number we first change the whole number into a whole number plus a fraction name for one (e.g. 5 is change into 4 plus 3/3). It depends on the denominator of the fraction of the mixed number.Skills: - Writing and reading decimals - Subtracting mixed numbers from whole numbers - Reducing fractions.Attitudes: - Cooperation as they participate in class and pair activity. - Respect for others and their ideas. - Awareness of new concepts learnt in lessons. - Confidence in math.Teaching Strategies / Learning Activities:Day 1 (lesson 33) - Have students work on multiplication facts to 121, set E.

- As a class go over the work. - Use illustrations and discuss the new concept with students. - Place a decimal chart on the board and go over the examples given on the book with students. - Involve students while explaining examples to come to the board and help solve the examples given. - As practice and assessment, have students work on practice set a – d.Day 3 (lesson 35) - Have students work on multiplication facts to 121, set G. Students will be allowed 5 minutes to work on the 100 problems. Check work as a class to find results. - Students work on the “Warm Up” exercises. - As a class go over the work. - Have students go to page 183. Discuss with students how to write fractions from decimal numbers. - Explain to students that one decimal place value after the decimal place has a denominator of 10, then 100, 1000 and so on. - Have students notice that the number of zeros in the denominator equals the number of decimal places in the decimal number. Example: 0.003 = 3/1000 - Tell students that the digits to the right of the decimal point are written as the numerator of the fraction. Explain that when one or more zeros come directly after the decimal point but before a nonzero digit, the zeros are not written in the numerator. - Write different decimal numbers on the board. Have students practice reading decimal numbers aloud. - Go over the examples provided on the book. - Have students work on lesson practice from lesson 35 - Go around checking students work and helping those who might have any misunderstanding.Day 4: assessment - Students will do the mixed practice of lesson 35 as part of their weekly evaluation (test) - Note that one of the groups will do it the next day (day 5)Day 5: lesson 36 - Have students work on multiplication facts to 121, set H. Students will be allowed 5 minutes to work on the 100 problems. Check work as a class to find results. - Students work on the “Warm Up” section.

Week 18Subject: MathematicsLesson Topics: Adding and Subtracting Decimal numbers; Adding and Subtracting Decimal Numbers andWhole Numbers; Squares and Square Roots; Multiplying Decimal Numbers; Using Zero as a Placeholder;Circle GraphsPrevious Knowledge:Students are aware of decimal numbers and can read and write them.Objectives:Through discussion, cooperative learning, individual work and use of illustrations, students will be able to: 17. Add and subtract decimal numbers. 18. Write a whole number with a decimal point. 19. Add decimal numbers and whole number. 20. Subtract decimal numbers from a decimal numbers. 21. Square a number. 22. Use the exponent 2 to indicate squaring or square units. 23. Simplify and expression by applying exponents and then adding, subtracting, multiplying, or dividing. 24. Find the square root of a number 25. Multiply a decimal number by a decimal number. 26. Multiply a decimal number by a whole number. 27. Use zeros to fill in each empty decimal place when subtracting, multiplying, and dividing decimal numbers. 28. Use zeros as placeholders as needed when writing in digits the word form of a decimal number. 29. Interpret information displayed in a circle graph.Concepts: - We line up decimal numbers for addition and subtraction by lining up decimal points. - To find the sum of a decimal number and a whole number, write the whole number with a decimal point and line up the decimal points before adding. - Squares and square roots – from the model of a square comes the expression “squaring number.” We square a number by multiplying the number by itself. “Five squared” is 5 x 5, which is 25. To indicate squaring, we use the exponent 2. 52 = 25. “Five squared equals 25.” Notice that the exponent is elevated and written to the right of the 5. An exponent shows how many times the other number, the base, is to be used as a factor. In this case, 5 is to be used as a factor twice. - A number is a perfect square if it has a square root that is a whole number. Starting with 1, the first four perfect squares are 1, 4, 9, and 16. - The number of decimal places in the product is determined by counting the total number of decimal places in the factors. - When subtracting, multiplying, and dividing decimal numbers, we often encounter empty decimal places. When this occurs, we will fill each empty decimal place with a zero. In order to subtract, it is sometimes necessary to attach zeros to the top of the number. - Circles graphs, which are sometimes called pie graphs or pie charts, display quantitative information in fractions of a circle.
