7 is equ to 8 30 - 12 is equ to 18 50 - 25 equ 25 6 * 4 is equ to 24 9 * 7 is equ to 63 [Musika] 12 * 5 is equ to 160 24 / 6 is equ to [Musika] 4 45 / 9 equ to 5 81 / 9 is equ to 9 Let's have activity number one pick and Match objectives complete number sentences to represent number properties and number facts materials needed worksheet and pen instructions look at the table match the pair of numbers at the bottom and write the sum number 1 3 + 7 + 4 is equ to 10 + 4 the answer 14 number two 1 + 9 + 3 is equ to 10 + 3 the answer 13 number 3 2 + 8 + 9 is equ to 10 + 9 the answer 19 number 4 4 + 6 + 2 is equ 10 + 2 the answer 12 number 5 5 + 5 + 6 is equ to 10 + 6 the answer is 16 Day 1 2 2 represent equivalent number [Musika] facts equivalent number facts equivalent number facts refer to number sent that yi identical numerical outcomes or results when computed despite variations in the arrangement or composition of numbers and operations example number 1 9 + 3 equ 12 7 + 5 12 TH 9 + 3 is equ to 7 + [Musika] 5 example number 2 27 - 12 e 15 30 - 15 equ 15 thus 27 - 12 is equ to 30 - 15 [Musika] example number 3 5 * 4 equ 20 2 * 10 is equ 20 thus 5 * 4 is equ 2 * [Musika] 10 example number 4 15 / 3 equ 5 40 / 8 is equ to 5 thus 15 / 3 is equ to 40 / 8 example Number 5 9 + 3 12 8 10 - 6 is e 12 thus 9 + 3 equ 18 - [Musika] 6 example number 6 determine the value of n in the number sentence 8 + 12 is equ n * 4 solution 8 + 12 n 4 that's 20 n 4 to get the missing factor 20 / 4 equ n the answer is 20 / 4 is equ 5 therefore N is equ 5 example number seven determine the value of n in the number sentence 64 - 8 e 25 + n solution 64 - 8 e 25 + n that is 56 e 25 + n to get the missing addend 56 - 25 is equ n answer is 56 - 25 equ 31 therefore N is [Musika] 31 lesson activity find the value of n so that the number sentence is true number 1 27 - 6 n * 3 number two n / 7 is equ 12 - 8 number 3 45 / n 19 - 4 number 4 8 * 9 equ 6 * n Number 5 34 - n 99 - 78 Now let's find the n Let's have the answer number one 27 - 7 is equ n * 3 the answer 21 / 3 7 therefore N is equ to 7 number two n div 7 equ 12 - 8 the answer 4 * 7 is e 28 therefore N is equ 28 number 3 45 / n 19 - 4 the answer 45 / 15 is equ 3 therefore N is equ 3 number 4 n * 9 is e 6 * n the answer 72 / 6 e 12 therefore n equ [Musika] 12 Number 5 34 - n 89 - 78 the answer 34 - 11 is equ to 23 therefore N is equ 23 Here are the answers number one seven number 2 28 number 3 3 number 4 12 and Number 5 23 [Musika] day 3 to 4 properties of addition and [Musika] Multiplication look at the two numbers and solve for the sum difference product and quotient 6 + 5 is equ to 11 11 + 9 [Musika] 20 11 + 19 is equ to 30 15 - 8 is equ to [Musika] 7 40 - 12 equ to 28 45 - 20 is equ to [Musika] 25 7 * 4 is equ to 28 7 * 7 equ 49 12 * 3 equ to 36 36 / 6 is equ to 6 45 / 5 equ [Musika] 9 60 / 6 is equ to 10 study the following table 1 operation addition number sentence 13 + 2 15 2 + 13 15 Multiplication 5 * 6 equ 30 6 * 5 30 addition the sum of 13 + 2 + 5 is e 20 13 + the sum of 2 + 5 is is equ to 20 Multiplication the product of 3 * 1 Tim 8 equ 24 3 * the product of 1 * 8 is equ to 24 commutative property of addition commutative property of addition states that change the Order of the add does not change the sum example 4 + 5 is equ to 5 + 9 both give 9 so the order does not matter commutative property of Multiplication commutative property of Multiplication states that changing the Order of the factors does not change the product example 3 * 7 is equ 7 * 3 both give 21 so the order does not matter associative property of addition associative property of addition states that changing the grouping of addends does not change the sum example the sum of 2 + 3 + 4 is equ 2 + the sum of 3+ 4 both give 9 so changing the grouping does not change the sum associative property of Multiplication associative property of Multiplication States the changing the grouping of factors does not change the product example the product of 5 Tim 2 Tim 4 is equ to 5 Tim the product of 2 * 4 both give 40 so changing the grouping does not change the [Musika] product worked example instructions fill in the blanks to make each number sentence true example number one 13 + 19 is equ to 13 + 19 example number two 5 * the product of 3 * 4 is equ to the product of 5 * 3 * [Musika] 4 example number three the product of 27 * 9 + 12 equ 27 + the product of 9 + [Musika] 12 lesson activity find the value of n in the following number sentences answer this in your notebook [Musika] [Musika] here's the solution and answer number one n + 12 is 32 the answer is n equ 20 number two 2 Tim the product of 3 * N is equ 18 the answer N is equ to 3 number 3 n+ the sum of 17 + 25 equ 51 the answer is n equ 9 number 4 7 * n equ 42 the answer is n equ 6 Number 5 n Tim the product of 3 * 2 is equ to 54 the answer is n equ [Musika] 9 day 3 to 4 learners takeaway and formative assessment learner's takeaways think and write in your notebook list three things you learned from today's lesson first properties of addition and Multiplication and second represent equivalent number facts learner's takeaways the mathematical skill or skills that I discover within myself while doing the activities that I want to improve most is or are blank because blank answer this in your [Musika] notebook fill in the missing number so that the number sentence is correct answer this in your note [Musika] notebook learner takeaway solution and answer number one the answer is three number two 17 number number 3 46 number 4 4 and Number 5 [Musika] n Maraming salamat sa panonood Hwag kalimutang i-like at mag-subscribe para sa higit pang educational content i-click ang bell icon para ma-update ka sa a mga bagong video salamat [Musika]
