In the formative years, a child develops effective skills through play and games. We live in an age where a child spends a major chunk of their time online and on the computer. Online math games and math puzzles are a great way to develop a foundation for math skills in a playful manner and are in alignment with the core curriculum.
A grade 4 child, is now proficient with the mathematical world. The child learns to represent math problems dealing with an addition in multiple ways including numbers, words (mathematical language), drawing pictures, using objects, making a chart, list, or creating math equations using relevant math symbols, etc.
As the fourth grader develops their mathematical skills, try to use clear and precise language in discussions and establish proper reasoning.
In grade 4 mathematics study:
An abacus is one of the oldest and most useful math aid for representing numbers and doing various mathematical operations. It can be used for teaching math based on core curriculum as a manipulative.
In grade 4, the abacus is handy in representing 4-digit to 7-digit numbers. It makes use of the place values. According to the US place value system, the place value chart is divided into periods and places as follows:
The above number pictures represent 4 -digit number place values and representation using the abacus. Each stem of the abacus can take 9 unit balls. So, the largest 4 digit number will be formed by placing 9 unit balls in each stem, i.e. 9999.
Each period has three place values
Thousands period: thousands, ten thousands and hundred thousands
Millions period: millions, ten millions and hundred millions
A million is a 7 digit number. The largest 7 digit number is 9999999.
Grade 4 math study will not go beyond 1 million.
We can add any two number with the help of the abacus which involved regrouping also.
Now consider any two numbers;
Step 1: represent the numbers on two different abacuses.
Step 2: Transfer the beads from one abacus to another starting from the ones place and moving up to the highest place value, keeping in mind that 10 ones’ is equivalent to 1 ten; 10 tens’ is equivalent to 1 hundred and so on.
In this example, the numbers at the one’s place are: 7(addend 1) +5 (addend 2) = 12,
Now 12 = 10+2, thus, one bead is added to the ten’s place of the final sum and 2 beads are left in the one’s place
Let’s move onto the ten’s place now, 1 (from carry of the one’s place) + 2 (addend 1) + 4(addend 2) = 7
The numbers in the hundred’s place for both the addends = 6 (addend 1) + 2 (addend 2) = 8
The numbers in the thousand’s place = 3 (addend 1) + 3 (addend 2) = 6
Addend 1 has a digit at the ten thousand place whereas addend 2 is a 4 digit number, so taking it as 0 = 4
Thus, the sum is = 4 6 8 7 2
Any number whether 4-digit or 7 digits can be split into parts according to its place value. For example;
Place value cubes and unit cubes as a helpful math aid and teaching manipulative for solving an addition problem stated as per the core curriculum.
Look at the example given below, where it is required to find the sum of two numbers 4655 and 2769. These numbers are first represented using place value cubes and then put together to form a sum.
Suppose there is a math addition problem involving any two 3 digit numbers.
Say, for example, take a simple case of 3 digit addition with regrouping,
455 +380
Well in case of such a first trial would be to note down these two numbers on a piece of paper and start and start solving by adding one by one from the least place value digit.
Another way can be doing the math sum mentally by applying simple mental math strategies without the help of any pen or paper.
What are the two numbers?
455 and 380,
So now if 20 is added to 380 it makes to the nearest hundredth i.e. 400
Thus, breaking a number into parts and then adding. Here the number 455 is broken into two parts (435 and 20) so that this 20 is added to 380 to make 400.
This utilizes the associative property of addition.
455 +380
= (435+20) +380
= 435 + (20 +380)
= 435+400
Now the addition of two numbers becomes simpler than before. Looking at different place values, in the addend, the tens and one’s place value is zero.
435+400 = 835
Is the final answer to the addition of 3 digit number problem?
Isn’t it easy?
Let’s try for a 4 digit number addition with regrouping.
In this math problem, the child learns to identify and generate a given number sequence or pattern.
For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.
Kids investigate different patterns to find rules, identify features in the mathematical patterns, and justify the reason for those features.
Example:
Rule: Starting at 1, create a pattern that starts at 5 and adds each number by 5. Stop when you have 6 numbers
In this math problem, the children use addition with the previous number to generate the next number and the
Step 1: Make sure the bottom numbers (the denominators) are the same.
Step 2: Add the top numbers (the numerators), put the answer over the denominator.
Step 3: Simplify the fraction (if needed)
At Fourth Grade, children enjoy exploring Math with fun Math activities and games. Children will enjoy completing these Math games and Free 4th Grade Math worksheets whilst learning at the same time.
It’s a very simple math game as well as math educational activity for a 4th grader. Divide the class into 4 teams. Lay down 8 cards in pair of 4 in front of each team. Create an addition problem with two 4-digit numbers.
The team is given time to add the two numbers. The one which gets nearest to or sum as 5000 wins.
Play more rounds, the team that wins the most will win this math game.
1. Spin and Win:This is an interesting math learning game for kids. Add 3 digit numbers to two spinning wheels. Drill a hole in the middle of each spin wheel and attach it to a sheet or a white paper board using paper clips.
Paste a pointer with each spinning wheel. Spin the wheels and add the three digit numbers on each of the wheels.
The numbers on the spin wheel can be changed to 4-digit numbers. In this way, the math addition problem can be changed to the addition of 3 digit number and 4 digit number.
