Today we started a 3-day project called the 1000s Project…
The project has been modified from the resource book by Julie Pier Brodie called “Constructing Ideas about Large Numbers” by Creative Publications.
We started the lesson by watching a keynote presentation that prompted students to ask questions about the images they saw:
Some comments they made as each image popped up were:
“They are organised for counting”, “They are in rows”, “You can count them”
One student ventured that they all showed 100, which revealed to me that their concept of 1000 was actually quite small!
Students were divided into groups and told that for this project they must do 2 things:
1) Collect 1000 of something
2) Organise a display for these 1000 items that proves there are 1000 items.
Students got to work and brainstormed a lists in their groups.
Despite some of the more challenging suggestions from groups (socks, laptops, books), students chose realistic and achievable items to reach their goal.
Students drafted other materials they would need, as well as how they would organise and display their work. The latter was much more challenging and required teacher guidance for most groups. Many were planning on simply bringing 1000 items and displaying them on a table or floor! We worked in groups to discuss how numbers are organised for counting and by the end of the lesson students had drafted a method to organise their 1000 items.
They have 2 days to bring their materials to school and will construct their display during math time.
Today we also started looking at a concept I coined “Celebrity Numbers”. I created an activity that allowed students to visually explain their thinking to guide and display their understanding about the ‘celebrity number’ 100. Students completed a “DCWRC” sheet:
D = Draw it
C = Calculate it
W = Write about it
R = Reflect on it
C = Connect it
Students chose to work alone or in pairs to display their thinking. Their drawings and calculations reflected a lot about their understanding and also revealed some areas we need to review in Grade 4 before moving ahead. Overall, it was an excellent way to see their strengths in math and many students enjoyed challenging themselves to create complex number sentences and word problems!
Here are some samples of the work they did:
It was evident that making connections to other numbers was challenging. Very few were able to link it to other base 10 numbers, so that is definitely a cue to review some of the basics after 9 weeks of holiday!
‘About Me Puzzle Piece’
The rest of the day we continued to work on their puzzle piece (description from previous post) and many are partway through their cutting and pasting of the acronym for PUZZLE.
Overall it was another busy but productive day in 4J!
