Welcome to my blog, this week we are going to talk about decimals, something new that we started.
We’re going to give you a little tutorial with decimals, dividing and multiplying with decimals but with the power of ten, or for short exponents, we have a chart that helps us, the left represents multiplying, but to the right is where the dividing happens. I’ll leave two problems down below for you to solve!
4.5 x 10² = ______
12.345 x 10³ = ________
I'll leave the answers in the next post!
Hi im back, today i'm going to let you know about multi-step fraction problems.
Also we are doing Greater than, less than and equal to kind of problems.
Sorry that I was not letting you about math because we were in vacation that why.
Multi-step problems is where you solve a word problem, but it has more than two steps. For example maybe you have to first add or subtract, then multiply then subtract or divide or add again until you answer the entire question.
Greater than, less than and equal to is when you find a multiplication sentence and you compare it to one fraction to see if it greater than less than or equal to.
I made a problem for you all to solve on your own. Once you get your answer, then write it in the comments and I will let you know if you got it correct next week.
Pedro is painting designs on his bicycle. He bought 20 pints of green paint. He used 1/4 of it for the front of the bicycle and 2/5 of it for the back. He needs 9 2/4 pints of green paint to paint his cousin’s bicycle. How many more pints of green paint will he need to buy?
HI i'm back so today I'm going to let you know about multiplying fraction with whole number.
This week the methods we use are standard and bar model. To multiply a fraction with a whole number is when you multiply a whole number by a fraction. So like ½ times 3 equals 1 1/2. Your answer will also be lower than whole number like the answer I got 1 1/2 this is lower the whole number 3.
I asked my classmates about how they are doing with multiplying fractions...
Q: Which method works best for you ? (Bar model or standard)
Jacob said, "Standard since you just have to multiply straight across, so it's easier for me’’. Kevin C said he likes standard as well for the same reason.
My classmates have the same opinion as me because I also like Standard because you see what to multiply weight on your paper.
See you in 2019,
Hello, it is Justin back at it again with another math blog for this week.
Currently this week we are solving multi-step word problems with fractions. So what we do to solve multi- step is read the problem and figure out what is missing and what we know. Then we when you use common denominators so we can work with the fractions. Then to get the answer, you get are answer then you have to add or subtract. Once you have that total, you subtract it from the whole (for example 15/15, which is a whole or 1). the total And then you get your final answer! It is a lot of steps, but once you practice it, its not so difficult.
I asked some of my classmates a few questions.
What is the most difficult about working with fractions?
Kevin C..c said that subtracting a whole is difficult for him.
What do you still need to practice (with fractions)?
Daisy said she needs to practice is estimating fraction.
This is all today in math.
Hello my name is Justin and I am 5th grade student from class 5-505. I’m a math blogger. This is my first time being a blogger so excited to be a blogger this year. I will be happy to show my classmates.
This month in math we are doing factions like estimating fractions, adding fractions, subtracting fraction, and practicing solving word problems with fractions.
Let me break it down for you. Estimating fraction is when you use a number line and we put a one baseline number to the left and in the middle we put one in a half and two go to the right because it is the whole. Then you put the number you are estimating has on the number line and see which baseline it is closest to.
Adding fractions and subtracting fraction is when to have to use common denominator by finding the multiples. Then when you have to add or subtract the fraction and you can get your answer.
I asked my classmates some math questions.
Q: What is your favorite thing to do in math?
Kevin C: My favorite thing for math is division because it is easy for me.
Jeremy: My favorite thing in math is multiplication because it is more interesting.
Til next week…
