Grade 2 & Grade 3 Two digit number
Here are 3 powerpoints I promised to share. Two are about developing the 2 digit imagery with your students. The third is just some images to use to use as warm ups or practice.
Get in the habit of building lists of expressions as students explain what they see, then encouraged students to look for patterns in the lists so they are focused on organizing data. Place value is not just naming positions, it is understanding relationships.
This powerpoint is meant to guide your thinking, if you choose to show it to students remember they need to experience building with the blocks. another-way-to-introduce-the-grid

I have sets of hundred grid tasks, number line tasks and guided math student sheets to accompany the materials. My goal is to reduce student colouring and increase their attention to seeing and mentally manipulating NUMBER.
The samples below are Grade 2 thinkers as they solve problems that involve two digit numbers. This thinking has developed from understanding the imagery of the grid.
NEW Oct 27 to site: LESSON PLAN Here is a tabloid size lesson plan for the introduction to dot collections I did with Grade 1 & 2. It is easily adaptable to Kin and Gr 1 who would stay with 5 or move to 6 instead of 7 for the first introduction…BE CAREFUL DOWNLOADING that your printer is set to tabloid and your page is set to 100% for the print so that it fills the page.
I do not mind you sharing with staff but do not randomly pass out my pdf’s. Please give colleagues a copy not the whole file.
The powerpoints I share are for your use. Yes, you may share with your team at your school. Please do not alter my slides and leave my information in the footers. I am concerned at how much materials get altered and dumbed down when public access is made available. As you all know I put thought, reflection, experience and research into all that I do and it is not made more simple for a reason. I WANT TO ENGAGE ALL LEARNERS IN THINKING… that takes time and perseverance from us and from them…
The handouts from Tuesday are in this file: st-clementine-augustine-ws
These are mazes. It is a great internet site. I am giving you a sample. Kids doing and building mazes on laminated copies so they can quickly re do is a nice addition to spatial reasoning work.
Ideas for Dot Collections. These ppts are meant for you to decide what to use and what not to use. They were not built to necessarily make sense to kids. Only show slides that you find useful to the students. Otherwise you learn and reflect from watching them. I start with 6 or 7 to give a challenge. If you start from 5 or less the students are quickly convinced this is not really a challenge and your high flyers will not see the power in thinking in collection. I spend time on one quantity, with lots of practice seeing different ways and comparing to the number before and the number after. That is why I had 6 and 7 collections in my handout. Compare, Compare, Compare.
THIS IS THE IDEA OF INTRODUCING INVERSES TO DOT COLLECTION WORK whats-covered-cards-early-grade-one
THIS IS THE ORIGINAL WHAT DOES NOT BELONG BLACK AND WHITE FILE… CHECK IT OUT IN CASE YOU HAVE A DIFFERENT VERSION…THEY DEVELOP SOME BASIC THINKING
THESE ARE SOME NEW WHAT DOES NOT BELONG IN COLOUR. I AM NOT SURE I LIKE THEM ALL SO BE CAREFUL. YOU DO NOT HAVE TO USE THEM IN ORDER. THEY ARE A VARIETY OF COMPLEXITY.
