Note: Every year we notice students need more handson experiences in uncovering the organization of our base ten system. We also notice that they seem fragile with subtraction. Our third grade team is building in more time in 20162017 for students to work extensively with addition and subtraction attempting. However, it would be a good idea for you to spend some time this year on the 4th grade Common Core standards specific to procedural fluency with addition and subtraction. In addition to the experiences in this unit, focusing on subtraction strategies during your Number Talks would be a great thing to do. Students in third grade have used base ten blocks and drawings, the open number line, and a variety of strategies to decompose numbers and subtract in ways that make sense. Some of the students also use addition for solving subtraction problems.

Multiplication Fact Practice
You can go to the Math Fact Fluency tab on the main Curriculum and Assessment page to get some ideas for an effective system. Additionally, here are some links to games for math practice while you are focusing on addition and subtraction for your core lessons. NC Game Packet/Pathways/Times Ten/Mult.

Lessons 6  8 focus on strategies with addition and some of the practice pages might be worth doing (We have found the rapid march through procedures to confuse students and we prefer the Investigations approach. ) Digital Resource: They have a nice digital resource in Think Central. In the Digital Resources Section, choose Base 10 and then click Add.

Sports Connection We should be do something interesting with the Sports Connection on TE page 44. It's about the seating capacity of football stadiums. With the controversial Chargers stadium, let's discuss how to put together an engaging math research project into stadium seating capacities and perhaps even ticket sales earning potential of each stadium.

Lessons 9  14 explore different methods of subtraction with a lot of practice using the U.S. traditional algorithm. It would be worth pulling some of the practice pages. Pay attention to the Home School Activities. They are all about distances and might connect nicely with Investigations' Thousands of Miles in Investigation 3. Unit Review and Test
