What? More Subtraction?

Yes! 

How lucky are you???

Today we are going to use that 100s chart again to think about subtraction as skip counting backwards. Since we are working on place value, we are going to focus on 10s. 

Here you have a video with a short explanation, don't you love her accent?

CLICK HERE

Now do page 2 of the math problems from last time. 

CLICK HERE

Don't forget,  do page 2! 

To solve the problems also use the splat 100s chart and make a splat each time you count back by 10. Or you can print out this 100s chart and color it in the old fashioned way.

And let's finish up with a fun game subtracting 10s from 100. If the cheering is distracting, you can always mute your device. But who doesn't love people cheering for them now and then?

But What About Subtraction?

Yes, I know, we've been doing a lot of addition and you're wondering when you get to practice subtracting. Well you don't have to wonder any more, today is the day!

Let's do some more skip counting. Use this 100s chart...

CLICK HERE

Start on 85. Pick a fun color and make a splat by skip counting back by 10s to the last number you can on the chart. What do you notice? How does the number in the 10s place change? How is that the same from when you skip counted up? How is it different? Now try some different numbers. Start with 42, start with 88, do you see a pattern?

Fruit is good for you, especially if it's mathy fruit! Play level 3 of Fruit Splat a few times. If you feel up to a challenge, try some higher levels!

And finally let's do page one of these problems...

CLICK HERE

Think about when you skip counted backwards. Does that help you with these problems? How? What happens to the number in the 10s place? What happens to the number in the 1s place? 

Wonderful Weekend!

You're back! 

I'm so glad you came!

We are going to take it easy today, you've been working hard!

Try this fun bingo game. It's pretty easy but the creatures are cute...

CLICK HERE

Then we have a quick video...

CLICK HERE

and let's do page 2 from this set of practice pages...

CLICK HERE

That's it for today. Go out and get some fresh air!

It's time to swim!

Today we are going to warm up by swimming with the sharks...

Start with numbers up to 99. 

If you are feeling super mathy, try numbers up to 999.

 CLICK HERE to play the game. 

Ok, now let's do some coloring. Go to this cute 100s chart...

CLICK HERE

Choose the 1-100 chart. Pick a color. Start with 4 and skip count by 10s (so add 10 each time, 4, 14, 24 etc). What do you notice? Which number changes when you add 10? Why is that? Now start with some other numbers. Is the pattern the same? 

And now for some good old paper and pencil practice. When you are figuring out these problems, think about that 100s chart, are you adding tens? Is there an easy way to do that? What about the sharks, when you had to count those blocks, did you count by 10s or 1s? Can that help you with the problems?

CLICK HERE for the complete set, but just do page 1, we'll work on the rest later. 

Hello & Welcome Back!

It's super cold out today, so let's warm up with this game...

Play just one round of level 1 Place Values

CLICK HERE

Ok, now that you're all toasty warm, take a look at this video about adding double digit numbers, watch carefully because you'll be doing some next. You can watch it as many times as you want. Isn't the internet great?
