Daily Math Investigations Part 2 took place in Surrey on November 21, 2013. Around 70 dedicated teachers left their classrooms and report card writing (some very eager for a break) to explore, discover, share and network together.
The focus of the session was on ‘Rich Routines’ from Daily Math Investigations.
Rich Routines are:
open-ended thinking tasks done in larger groups
more structured, but not boring
concepts worth revisiting
increase in complexity as they are explored over and over
active and engaging for all students
Rich Routines are questions/investigations posed during a whole group time. We have suggested a variety of routines that are predictable in nature but are engaging and open-ended enough to meet the needs of all the students. Here are some of the routines we discussed from the resource:
All About Number
Exploring the Open Number Line
Exploring the 100’s chart
Numbers of the Day
Messing with Data
Sort it Out
Teeter Totter Tales
Check out the new Entry Tasks that were introduced at yesterday’s session.
Many of the tasks were taken from the Numeracy Centre Fun section of the blog.
There is a new series of books called “Math in Nature” which journeys into the natural world. The wonders of nature are shown in vibrant cut paper collages that focus on important mathematical concepts. Each season focuses on an area of mathematics. There are many ‘What if?’ problems presented in the text.
On the day before Halloween (can you believe it!), 60 primary teachers gathered at DEC to discover and experience activities that promote number sense with Chris Hunter and myself. We emphasized the importance of differentiating the activities to meet the need of the students. Assessment for learning is another important aspect to consider when doing these activities with students. Ask yourself: What do I want the students to know, understand or be able to do?
Here are some of the activities that extended from the ideas in the book:
1. Guess, Check and Estimate – (focus on estimation, referents and skip counting)
Ask the students take a collection of objects and lay them on the bare tree
Ask the students to ‘estimate’ how many objects are on the tree board
Ask the students to make a ‘referent’ of 2, 5, or 10 and pull it away from the total collection
Ask the students if they would like to revise their estimation (after seeing the referent)
2. Bat Cave Pattern – (focus on patterning)
What patterns do you see?
How could you model the patterns using Cuisenaire rods? (or other materials)
Some students may need to lay rods directly on the book.
Some student may need to be challenged by changing the number of bats sleeping in each row (increasing by 2)
3. Making Ten Story Mats – (focus on partitioning and number operations)Ask the students to count out a quantity of 10 objects.
How many different ways can you make 10 in two parts?
What stories can you tell about your story mat? (I counted 5 leaves on the ground and 5 floating in the sky. How many leaves have fallen from the tree?)
What equations can you write about your story?
4. Roll, Build and Compare – (focus on comparing quantities…more/less/the same)
Ask the students to work with a partner.
Each partner rolls a 10-sided die and builds the quantity rolled on their 10 frame.
The partners compare their quantities. Who has more? less? Are they the same?
Ask the partners to determine how many more or less.
Cuisenaire rods are one of the mystery manipulatives. Often people ask me “What do I do with them?” Cuisenaire rods are a versatile collection of rectangular rods of ten colours, each colour corresponding to a different length. They can be used to develop a wide variety of mathematical ideas at many different levels of complexity. In working with the rods, children have a context in which to develop their communication skills. Explore and enjoy the power of cuisenaire rods with your students!
