# Today's Number: Ten Robot Shapes

What is today’s number? How many shapes do you see on the robot’s screen?

Can you count up to 10? Can you count back down to 0? How do you make 10 tally marks?

How many blue triangles do you see? How can you use tally marks to show that number?

How many yellow squares do you see? How can you use tally marks to show that number?

How many green circles do you see? How can you use tally marks to show that number?

Look around your home. Can you find or make sets of 10?

*Here are some ideas:*

*Line up 10 toys or objects. Make tally marks for each object.**Take one away from the line and count backward. Continue taking one away and counting backward, until you have no more toys left.**Write one number for each item in your set.*
