The class won a good behavior contest and the reward is a bowling party. The day of the party it is raining and the students are unable to visit the bowling alley. So the students build their own bowling alley using the WeDo robot kit. Then they have a bowling competition to see who bowls the highest score.
This resource accompanies our Rethink 2nd Grade Math Number & Operations in Base Ten unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.
This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Math for Number & Operations in Base Ten.
This short video and interactive assessment activity is designed to teach fourth graders about adding 3 numbers - word problems.
In this interactive, students practice adding up to four two-digit numbers using stragtegies based on place value and properties of operations by playing against students from around the world in a canoe race.
Find examples of whole number prices in ads in the newspaper or on the internet. Give students a target of $100 to spend. See who can get the closest by choosing 3 or 4 items. Once students have picked a set of numbers to add, ask them to tell how they added the numbers. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.
This short video and interactive assessment activity is designed to teach second graders about using real maps (english lengths and distances).
A learning road map is a great way for students and teachers to keep track of standards they have mastered. This road map is for grade 2 math cluster 2. It can be printed and placed in a data notebook. Students would then color in the circle to indicate their level of proficiency. It could also be used digitally where students would fill in the circle with color. Road Maps help students take ownership of their learning and help guide instruction for teachers. This resource was developed as part of a professional learning opportunity funded by the NCDPI Digital Learning Initiative Planning Grant
Sample Learning Goals
Improve understanding of place value by using different sizes of papers for ones, tens, and hundreds.
Develop mental math strategies when taking apart and putting together numbers.
Use the “make a ten” strategy when counting and doing addition.
Develop a mental model of the basic properties of numbers including commutativity, associativity, and closure.
This document is the About the Cluster document created by the authors of the NC2ML Instructional Frameworks. Read this document prior to teaching the cluster in order to get insight into the clustering of the standards, mathematics to be taught, and important considerations.
This document is not remixable since the document has been written by creators of the NC2ML Instructional Frameworks.
This resource is from NC2ML. It may not be remixed.This Standards Brief discusses strategies and representations second graders are taught for mult-digit addition and subtraction. This is a great reading to share during a professional development with teachers or to hand out during family math nights.
This is a blended unit based on Unit 3 of the second grade Everyday Math series.
This unit will focus on strategies for solving subtraction problems within 20. Students will learn strategies including: counting up and back on a open number line, using their knowledge of addition/subtraction facts within 10 to solve larger problems, and using doubles facts to solve subtraction problems. This unit builds on the last unit as students lean on their addition knowledge to help with subtraction. The big goal is for students to develop fluency with subtraction facts within 20.
