Keep going to set off on your number eight adventure!
Alright, young explorer!
Get ready for an exciting math adventure, where you will learn how to add eight to any number. Put on your explorer hat and grab your trusty math compass!
Your mission is to become the best math explorer and master adding eight to any number using your amazing math brain.
Like a real explorer uses a treasure map, you'll use math tricks to break down numbers into smaller, easier parts.
These tricks will be your secret tools for solving any number puzzle that comes your way.
Imagine you're about to unlock a special door with a special key. This key is called place value. It helps you see how numbers work together like pieces of a puzzle!
Watch this short video to learn more about the magic key of place value.
Yippee! You just unlocked the power of place value!
Now, you can see how numbers fit together and move from one number to another, like hopping from stone to stone across a river.
Come along!
Uh-oh, little explorer, as you were adventuring through the wild jungle of numbers, you lost your bag of coins!
You used your cool binoculars and spotted the bag of coins on the other side of the big river.
But don't worry! There are two big rocks in the water that you can step on.
But here's the tricky part: you need eight more rocks to hop across and get your bag of coins.
Use your secret math explorer tool to find out how many rocks you need.
The magic key helps you break numbers into tens and ones, making math easier and more fun.
To find the total number of rocks you need, add 8 to the 2 rocks you already have.
Look at these two blocks!
You have two ones here. These are like the two rocks you already see in the river.
Now, check out these blocks!
Here are eight more ones. These are the extra rocks you need to make it across the river.
Count the total number of blocks together.
Fantastic job! That's right, you see ten blocks in total.
That means you have ten rocks in total.
You used your amazing math skills to find the correct number of rocks as you hopped from rock to rock!
Woohoo, explorer! You did it; you got your bag of coins back!
Now that you've mastered place value, it's time to show off your skills.
Get ready to try the problems below and practice adding eight like the math explorer you are!
Great job!
Using place value, you can start doing math in your head; it gets easier every time!
This isn't just for your math adventure. You can use this in real life, too!
Imagine adding up your stickers, snacks, or even counting toys — you can use this trick to make adding faster and more fun.
But wait! Here's another trick: adding on a number line!
Check it out in this video!
Wow, you did an awesome job learning how to add a number line.
Using a number line is like having a magic map that helps you find your way through numbers.
A number line is like hopping from one number to the next, like a frog hopping across lily pads.
It helps you see how adding numbers works.
Look at the number line below.
Imagine your fingers are little frogs ready to hop. Start at three and hop eight spots.
Great job! You landed on 11. That means when you add 3 to 8, you get 11.
Easy peasy!
Now, start at eight and hop three spots.
Awesome job! You landed on 11 again, and even faster this time!
Here's a little trick: if you start with a bigger number, like 8, you'll get the answer faster.
The number line is a fun way to help your brain improve at adding numbers without always needing to count every single time.
By using your super brain, you'll be able to solve addition problems faster.
Fantastic!
