3rd grade students in the Advanced Math Program at Latin American School in Monterrey, Mexico share what they have learned in the first trimester of the school year 2022-2023.

This is What We have Learned

In this page what we need to do is round and then estimate the answer

Here you need to know if your multiplying, or dividing and say what number are you multiplying or dividing and at last you put the answer

Flash red

If you want to estimate the number 5,6,7,8,9, you round up and 4,3,2,1 you round down.

Round 11 to 10 Round 94 to 90 10x90=900 11x94 is about 900

Replace 11 with 10 Replace 94 with 100 10x100=1000 11x94 is about 1000

Is to add, subtract, multiply, or divide 

You need to know what are you adding, subtracting, multiplying, or dividing 

Problem Solving:Use objects and resolving

you need to do a pattern if it only had the triangle you will need to complete the pattern

the next shape needs to be an upside down shaded triangle then you need to put a not shaded square then a shaded square then a not shaded pentagon but there are 2 shapes that are missing the 2 shapes that are missing are an upside down shaded pentagon and a hexagon

In this lesson you first do a square with little squares inside.Then you first multiply the two first numbers like for example 53 x 85 then 5 x 3 then is 15 so you put a line in 15 squares and then you do the same with the others.

Estimating sums differences of whole numbers

You need to estimate to the greatest number or if is said that you need to estimate to the tens place you estimate to the tens place

example of this lesson is Pablo was going to a 54 kilometer trip he wants to know how many kilometers he’s gonna record from the first day to the last day how many kilometers does he passes in the first day and in the last day?

From the 108 kilometers he records he also wants to know how many liters of gas does he use in the 108 liters if per 1 hour he uses 30 liters?

Problem Solving:Draw a Picture and write an equation

You need to find the information and then draw a picture to do it easier and last do an operation like add subtract multiplay and divide

In this lesson you underline your basic facts for example 5 x 70 you underline 7 and 5 x 7 = 35 so then add a 0 and it is 350

Here are different ways to represent 555,612,300

Expanded form: 555,612,300=500,000,000+50,000,000+5,000,000+600,000+10,000+2,000+300

Word form:555,612,300= five hundred fifty-five million,six hundred twelve thousand,three hundred

The 6 is in the hundred thousand place, it’s value is 600,000

use a place-value chart to help you write a number in standard form.

Write four hundred twenty’s thousand,three hundred fifty-nine in standard form

Step 1: write 420 in thousand period                                       Step 2: write 359 in the ones place

Each digit in 420,359 has a different place value and value. The place value of the digit 3 is the hundred place. This digit has the value of 300

Problem Solving Missing or extra information 2-3

The missing information is a information that is missing like when it don’t tell you all the information 

And the extra information is the information the is more of what you need 

Rounding means to round to the number that is closer to the ones, thousand,millions,billions, etc…, 

Using money to understand decimals and problem solving make and organized list

by using money to understand decimals it means to put the numbers in expanded form 

by making an organized list we mean to put it in some certain orders

9.NUMBER SENSE How do you know that 35 x 5 = 5 x 35 without finding products? Because the commutative property of multiplication states that the order of the factors doesn’t affect the product

Explain how you know that in ? X 6,273 = 6,273, the ? will be 1. Because any number multiply by one is the same number

Science border

In this lesson you multiply the bottom number by the top numbers for example 7 x 49 multiply 7x9=63 put down the 3 and in the top the six so 7x4=28+6 34 so the answer is 343

In this page we need to do process with the parcial products if you have a multiple like this 4x291 the 4 is going to multiply everything

The lesson is about multiplying with 2-digit numbers so an example is 50 x 10 you underline the basic facts are 5 and 1 multiply them the answer is 5 then add the 2 zeros form the 50 and 10 so there you got the answer

https://api.bookcreator.com/users/v2/eeJCIScGBQhLd8TUcOnqQ71RPSe2/books/wFSTX7EbSS2VzGzFkATOjA/assets/ilg8qc4kRf-tfrk873Nc4Q.jpeg?width=530&height=252

Round to the nearest hundred thousand. Draw a number line on a separate sheet of paper to help you

Before finishing I will give you some examples 

Use breaking apart to find each product 1. 3 x 5 = 9. 4 x 6 = 2. 3 x 8 = 10. 4 x 9 = 3. 4 x 9 = 11. 4 x 8 = 4. 3 x 7 = 12. 3 x 9 = 5. 4 x 8 = 6. 3 x 6 = 7. 3 x 4 = 8. 4 x 4 =

the example is 48 x 38 and then you first multiply 8 x 8 is 64 you put the 4 and carry 6 and then multiply 8 x 4 is 32 you add the 6 the answer is 38 and then you put it with the 4 now it is 384 and then you multiply 

3 x 8 that is 4 you carry 2 then you multiply 3 x 4 is 12 add 2 is 14 put is together with the 4 so it is 144 you add them and the answer is

James has 12 seashells mounted in a row. The 6 shells in the center of the row are nautilus shells. Is there the same number of shells on either side of the nautilus shells? 

Yes, there are three shells on each side.

Here we just need to underline our basic facts then we need to add the number of 0’s our multiplication has

In this lesson what our process is reasonable estimating

It is like it says put 20 marbles in 4 groups and 4 divided by 20 is 5 so in 4 groups you put 5 marbles.

If you multiply 11times 5 it is 55 and 5 times 11 is the same.And if you divide 55 times 11 it will be 5 and 55 times 5 it is 11

What’s an expression? An expression is that you add or subtract or divide or multiply a letter for example rx6= 24 in this case the r represents the 4 that’s an expression

You need to find a rule and draw an expression

1. 7 x 3 = 3 x___ 2. 4 x 0 =_______ 3. 5 x 4 = 4 x___ 4. 2 x 1 =_______ 5. 0 x 7 =_______ 6. 8 x 3 = 3 x___ 7. 9 x 1 = 1 x ___ 8. 1 x 5 =_______

Commutative Property of multiplication: You can multiply any two numbers in any order Example:2x3=3x2

Identity property of multiplication when you multiply any number by 1, the product is that number Example:7x1=7

Zero property of multiplication when you multiply any number by 0, the product is also 0. Example:3x0=0

8x2=16 80x2=160 80x20=1,600 800x20=16,000

Subtracting hole numbers is like if you have 200 -123 if the number on the top is less than in the one in the bottom is greatest you give one ten Example:

By comparing whole numbers we mean to compare both numbers and then we add this signs &lt; &gt; we use them to compare numbers 

Ordering whole numbers by ordering we mean that u put the numbers in a order form  least to greatest or greatest to least

In this lesson you learn to multiply easier, because you first multiply the ones and then multiply the tens

 But to make it easier multiply 7x1 =7 add a 0 then 7x5=35 so 70+35 = 105

Multiplying 2-Digit Numbers by Multiples of ten

When you are multiplying by 2 digit numbers and 2 digit numbers with a 0 we need to do the process that is what I will show you

Remember when we &#160;are multiplying by 10 or another number with zero we need to add the zero at the end.

First underline my basic facts,Then the 10 became a 1,Next we multiply 17x1=17,Finally add the zero.The answer is 170
