How Much, How Many, How Far, How Heavy, How Long, How Tall is 1000?

Over the past several weeks we have been working on developing our number sense by working with numbers up to 1000.  When we first began we read the book "How Much, How Many, How Far, How Heavy, How Long, How Tall is 1000?" as an introduction to the concept of 1000.  Last week we reread the book to refresh our memories before creating a representation of what 1000 actually is.

Here is the book.

 We began by creating groups of ten.  Students received strips of paper to glue 10 toothpicks onto.  Students continued to do this until all of our strips (100) were complete.

Counting to make sure we had made enough.

We then counted by 10s all the way to 1000.  Each student put each "ten" in a line (or group) until we reached 100.  At that point we started a new line/group.  

Students placing their "tens" in groups of 100.

When we were all finished we could see exactly what 1000 looked like.

Happy Thanksgiving!

Today Room 20's day was filled with a variety of Thanksgiving themed activities.  This morning during our Math class, we worked on Thanksgiving Math.  We had three different activities.  One was ordering three-digit numbers, another was working with numbers to create a variety of three-digit numbers, and the third was an activity that had students practicing their addition.

This afternoon was our Thanksgiving Stations.  Six stations were placed around the room for students to work at.  There was a Thanksgiving Dinner station, where student selected items to buy for dinner.  They had a $25 limit and they had to choose items based off the prices.  There was a station for disguising a turkey, a station where students rearranged the letters in the word cornucopia to find new words, a reading corner filled with Thanksgiving books, an activity book station, and a Thanksgiving Math games station.  Everyone had a lot of fun!

Some Important Math Review

Over the past couple of weeks, we have been spending our Math classes reviewing some important concepts from Grade 1 and Grade 2.  

We began by reviewing odd and even numbers.  We watched two Math stories on the Smartboard, "One Odd Day" and "My Even Day", and then followed up by playing a game and working independently.

The next concept we reviewed is one of our Mental Math strategies, Count On.  This strategy is used when adding a 1, 2, or 3 to any number.  To practice this strategy we played two different Math games.  Count On Bump and Count On Colours.

 We have also been reviewing our number concepts and place value to 100.  We used place value dice to build numbers to 100 and then we examined a number line.  We placed some key points on our line, then placed numbers where we thought they would go.  We were all pretty good at this.  This activity will be used as a basis for the beginning of our investigations into numbers past 100.  Our next step is to expand our number line from 0-1000, using our first number line to help us.
