The Small Pumpkin

teacher102 — Fri, 16 Oct 2009 01:13:19 +0000

Today we counted the seeds from the small pumpkin – while our pumpkin soup was cooking in the crock pot. Yum! Well, first we made some estimates. We knew there were less seeds in the small pumpkin than the medium and large pumpkin by looking at the bags. Some estimates we came up with were 100, 150, 200, 300, 302 and 308. We had counted by 10s and 5s yesterday so today we counted by 2s. I gave each child a small handful of seeds and they put them on their desk in a line of 10 seeds counting by 2s. Then we added up all our groups and I made the seeds on the board. We counted 230 seeds. Next, on a piece of paper we made the number of seeds that the medium pumpkin had -480 seeds. We needed to count by 2s, 5s or 10s. When counting it is important to be organized so it is easy to count. We are really trying to be accurate. See below some pictures of our work in progress.

Counting Pumpkin Seeds

teacher102 — Thu, 15 Oct 2009 01:07:10 +0000

We had a fun math class today counting pumpkin seeds. Yesterday we opened up 3 pumpkins – a large one, a medium sized one and a small one. We stuck our hands in and pulled out all the seeds. We put the seeds into 3 bags. I took them home, cleaned them and toasted them in the oven so that they would be easier to count. So today we started with the seeds from the large pumpkin. I gave each student a pile and we put them in groups of 10. We decided we would count these seeds by 10s. After all the seeds were distributed we counted by 10s and the seeds totaled 440. We decided to count the medium sized pumpkin by 5s. This was more of a challenge. Again, I gave each student a pile of seeds to put into groups of 5. To count by 5 I put tally marks on the chalkboard. We counted 480 seeds. We sure had a lot of tally marks on the board. See some pictures below. Sorry but even though I had my camera ready on my desk today I totally forgot to take photos of all our amazing counting.

How many pumpkin seeds are in a pumpkin?

This week we will estimate how many seeds we think are in our pumpkins. We have 3 pumpkins – a big one, a medium sized one and a small one. How many seeds do you think we will find? Which pumpkin will have the most?

Working Together To Do Math

teacher102 — Tue, 29 Sep 2009 23:16:24 +0000

In Math we are counting and comparing 2 digit numbers. When we count large amounts we are learning to group objects in groups of 5 or 10 to make counting easier. We can count by 2s, 5s and 10s. We are practicing our math facts, too. At the same time we are learning to work in small groups and with partners cooperatively. We are doing great!

The 100th Day of School Today!

teacher102 — Tue, 17 Feb 2009 00:35:03 +0000

Today was our 100th day of school. We brought in collections of 100 things. We made 100 dots using bingo stampers. We made necklaces with 100 fruit loop cereal. We made lists of 100 words and we wrote our numbers to 100. At the end of the day we had a yummy cake. Food is so important when we celebrate.

Check out the Junior Crew’s blog in Australia. They celebrated today, too.

100th Day of School Tomorrow

teacher102 — Sun, 15 Feb 2009 16:06:29 +0000

Tomorrow will be the 100th Day of School. I am very excited to see everyone’s collections tomorrow. We will wear our 100th Day glasses and listen to everyone present their collection. We will also make necklaces using 100 fruit loops (cereal). I will be busy today baking a cake for you to celebrate the day tomorrow. I think I will put 100 gummie bears on top! Come to school tomorrow ready to do lots of counting!

Welcome to the Junior Crew in Australia. Even though this is only their 10th day of school they will join us in celebrating the 100th Day of School. Maybe when they really get to 100 we can help them celebrate. Who can do the counting? Will we still be in school? When will that be?

The 100th Day of School

teacher102 — Fri, 30 Jan 2009 03:57:06 +0000

The 100th Day of School is quickly approaching. It will fall on Monday, February 16th. Our class will be celebrating on this day with a “100 things collection”. Each student should start collecting things like pasta, stickers, cards, elastics, beans, buttons, pictures, etc. The collection can include 100 of the same thing, or smaller collections (groups of 10) of 10 different things.

The collections should be displayed neatly in a box, plastic sandwich bag, glued onto a posterboard, made into a book, or any other creative way that will be easy to transport to school.

We have been practicing counting every day. Here are a few collections to represent some of the numbers. We are learning to be organized and group objects in groups of 5 or 10 so it will be easier to count and our counting will be more accurate. Today was day 90.

You can also go to to see more collections of 100 for ideas by clicking on this 100th day wetpaint wiki space. Just hold your cursor over the unerlined words and click.

Have a go at making something, anything you like out of snow balls. The catch is that you can only use 100 balls.
100 Snow Balls
is a game that will keep you carefully counting until the job is done!

What do you think of my snowball creation?
I only used 50 balls. Can you use 100?
