5th Grade AMP 21-22Lesson 1: Place Value
Lessons: 1, 7, 20
Lesson 20: Probability
Lesson 7: Adding and Subtracting Fractions
By: Mateo C, Humberto and Jimena
Lesson 1-1: Place Value
Place Value is that a numbers value depends on where it is placed on a number
In this example the 1 has a greater value than the 7 because it is in the hundred billions place and the 7 in the ones place
Lesson 1-2: Comparing and Ordering Whole Numbers
When you start comparing whole numbers first check which one has a greater value by checking if the numbers have ones, thousands, millions, etc. and if a number has millions with billions the one with billions in bigger but if they have the same values then you need to be checking both numbers digit by digit from left to right and when there are the same numbers you continue. When you get different digits the one with the biggest digit is bigger
In this example the number in the right is bigger because it has a greater value in the hundreds place
Lesson 1-3: Exponents and Place Value
Exponents are numbers placed on the top right of a number and are for multiplying a number by itself the times the exponents shows
This is said as 6 to the 5th power and it is 6x6x6x6x6
Lesson 1-4: Decimal Place Value
Decimals are numbers that go before the decimal point and have a value of less than one. A decimal have different names instead of tens in tenths, instead of hundreds is hundredths, etc.
Lesson 1-5: Multiplying and dividing by 10, 100 and 1000
When you multiply by 10 you move the decimal point to the right 1 time, if you multiply by 100 you move the decimal point 2 times to the right and when multiplying by 1000 move the decimal point to the right 3 times and the same with division only changing that you move the decimal point to the left.
Lesson 1-6: Comparing and Ordering Decimals
When you compare decimals is the same as when you compare whole numbers
In this example the number of the right is bigger because it has a greater tenths value.
Lesson 1-7 : Make an Organized List
When you make an organized list you need to make sure that you use all the data you have and have it organized so it’s easy to understand
Lesson 7
7-1: adding and subtracting denominators.
When the denominators are alike, just add or subtract the numerators and place the result over the denominator. Now, the fraction can be simplified or written as a mixed number.
7-2: Least common denominator
The least common denominator is the smallest number of all the common multiples of the denominators when 2 or more fractions are given.
7-3: adding and subtracting unlike denominators.
First try to find a common denominator by multiplying the two unlike denominators by each other. Then solve it like you would a normal problem.
7-4: estimating sums or differences of mixed numbers
When you estimate a mixed number, you have to, for example 2 1/4 plus 3 6/8, first estimate 1/4, is it closer to 0, or 1? It’s closer to 0 so it stays as about 2, and 6/8 is closer to 1, so you add a number, so it’s 2 plus 4, which would be about 6.
7-5: adding mixed numbers.
Step 1: change into improper fraction.
Step 2: change to common denominator
Step 3: add the numerators
Step 4: change into mixed numbers
Step 2: change to common denominator
Step 3: add the numerators
Step 4: change into mixed numbers
7-6: Subtracting mixed numbers
Step 1: change into improper fraction
Step 2: change into a common denominator
Step 3: subtract the numerators
Step 4: change into mixed numbers
7-7: Make a table
tables are lists of numbers showing the results of a calculation with varying arguments.
