#### 2 Building Numbers with Base Ten Blocks

Have children open up the Number Pieces app.  Explain that you will be using the app as a tool to build numbers using base ten blocks.

Review how to move pieces onto the workspace and how to use the writing tools to record numbers.

Give students 5 minutes to simply explore the tool before asking them to begin building numbers as a group.

Ask children to clear their workspace.  Explain that you are going to say a number and you want them to show that number using ones and tens.  Begin with single digit numbers.

After they have had practice moving cubes onto their workspace, begin building 2-digit numbers.  Have them place 1 ten and 2 ones on their board.  Ask children to record the number they've built on their workspace using the pencil to write.  Ask for students to share their workspace with someone sitting next to them.

QUESTION:  Which digit changed when you added more ones?

ANSWER:  The digit in the ones place.

After practicing with adding ones, have students add tens and record the new number.

QUESTION?  Which digit changed when you added more tens?
