150 Chart - Many of our students are unsure of what comes after 100.  In fact, a common misunderstanding is that 200 comes after 109.  We have developed this 150 chart to help address this issue and expose children to numbers beyond 100.  The print shop can provide you with laminate desk versions.

Counting and Comparing

Snowman Math - I modeled these games and activities based on my work with Ladybug Math.  I used the book, The Biggest, Best Snowman by Margery Cuyler as a launch to some of the subitizing, counting and partitioning activities I did with Airport's grade 1 and 2 class. 

When working on comparing numbers - children drew three cards and 'built' three different snowman out of the indicated number of 'unifix cubes'.  Then then put their snowmen in order from smallest to largest and told a friend about how their snowmen compared.  I have attached a sheet the could be used as a summative piece - after LOTS of hands on practice.

Lots of Spots - Students have fun with the spotted animals in the book and choose lower numbers of spots to count and add together to create a teen number to represent.  Students use the Teen Number Mat to display their representations.

 Balancing Act  by Ellen Stoll Walsh.  This clever, few words on the page can easily be linked to concepts about equality, adding, subtracting and partitioning using concrete, pictorial and symbolic representations.  Using the analogy of a teeter totter to discuss equality and inequalities  we can lead into the use of a scientific balance, number blance and the balance cards.

One is a Snail, Ten is a Crab - This engaging counting by 'feet' book written by April Sayre, gives children lots of prediction opportunities.

B.C. PLOs A1 and A4

Sue Bannister was getting ready to do One is a snail, Ten a crab (her all time favorite math story) with her class and decided to rebuild the animal cards. She has found that with younger kids that she wanted them to be able to quickly find the animal they needed such all the crabs,so she built the following pages so she could colour code the animals. on card stock.  She included a little legend so each child now has their own ziploc pack. She hopes it'll last for a few years and plans to 'squeeze out' every possible learning experience she can with resource!!  (Thanks Sue for sharing!) Legend, snail, feet, dog, insect, spider and crab cards.

Part Part Whole Thinking

Here is a clear explanation about Part Part Whole Thinking and its importance.  A child who can partition a number is one who is well positioned to understand place value.

The description and activities come from TeachMath.  The Part Part Whole cards are made in our print shop if you would like to order a set printed on bright manilla tag.  See the number operations section below for cards that relate to the story problem activities.

Thanks to Campbell River for sharing these cards with us.  Mary developed them after her First Steps Training.  They help to identify the value of the digit and can be copied so that each child has a set.

Part Part Whole Game - Peek-a-Boo Pennies

Thanks Andrea for sharing this game with me.  Andrea's grade one students really enjoyed this game and with adaptations it should work well for grade two.  You could use dice or number cards. It can easily be extended to include nickels and dimes for skip counting totals.

The Cheerio Counting Activity - Develop Number sense with this lesson, which leads well into place value activities.

Please note:  We discovered that Cheerio brand cereal o's only fit 40 o's per zip tie where as 'Generic'Brands can fit 50 which is easier for young children to count.

Skip Counting

Many of our children haven't realized that skip counting is just an effecient method of counting and the number they get whether counting by 1's would be the same as if they were counting by 2's, 5's or 10's.  We feel that it is very important to keep objects attached to their count to reinforce this important skill.

Thanks Jocelyn for sharing this lesson with us and thanks Marty for ordering more of these books!

Parking Lot Stories

 

This series of lessons provides an example of how to playfully connect skip counting, partitioning, adding, subtracting, equality within the context of parking lot number stories.  Suggestions about the gradual release of responsibility and ways to differentiate are also included.  This is also a kit that can be ordered from the LRC (KT513 PLA)

2-Digit Addition/ Subtraction Strategies  These strategies have been co-created with students.  Choose a book like Garbage Barge, 365 Penguis... drawing the context and numbers and stories from the book.  As students perform their operations, discover and discuss their thinking.  Name those strategies and refer to them, so that everyone can practice each one.  Once a list is compiled and students have used them, provide other story problems to practice selecting the best strategy for each questions.   B.C.

Thanks to Jeannie DeBoice of Sooke for joining us on our Pro-D day and allowing us to post this valuable resource.  When used with explicit strategy instruction, strategy practice and then strategy retrieval practice, students will improve their recall of basic addition facts.

Our print shop has sets of these cards available, but I have attached the files for you to print your own if you wish.

 My Addition Strategies  From the addition strategies that you have co-created and named with your students, you can create a strategies mat.  Students can use recipe cards to write out "just right" number questions and then place their card on the strategy they used to determine the correct answer.  Partner work is great for this activitiy and we easily observe which strategies our students feel comfortable with.

Co-Creating Addition Strategies It is crucial that students explain the strategies that they use to find sums and that our mathematicans select an efficient strategy depending on the addends given.  This lesson uses a context, base 10 materials and an open number line so that students share their thinking to co-construct a class set of strategies. This co-creation increases student ownership and meaningful understanding of the strategies.
