This resource accompanies our Rethink 1st 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 1st Grade Math for Number & Operations in Base Ten.
In this Khan Academy interactive, students will add 1 or 10 to a two digit number.
Students roll number cubes and strategically create numbers, mentally adding or subtracting to make target numbers on a hundreds board. 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 lesson reviews the concepts of counting beyond 100 by counting by 10's with tally marks. The shoe collection associated with it began in lesson 2. This lesson also allots time for students to count all the shoes around the school with the teacher's help and to take action in the last step of the shoe collection to help others in the world by bagging up the shoes for transport. The action taken by the students produced a large number of shoes to donate. The final part of this lesson and unit is to complete a reflection assessment.This lesson was developed by James Agner as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.
The shoe collection associated with the unit continues and students will put out more shoes around the school in pairs of two. This lesson reviews the concepts of counting by adding two, five, and ten. It introduces a way to count numbers quickly by using a Ten Frame to count fives and tens and introduces a game called 100 Hunt.This lesson was developed by James Agner as part of their completion of the North Carolina Global Educator Digital Badge program.

Grade 1 Module 4: Place Value, Comparison, Addition and Subtraction to 40. Contains 29 Lessons.
This assessment task assesses students' ability to mentally find 10 more or 10 less than a number without having to count and explain their reasoning.
Students practice using mental math to find multiples of 10 more or less to find a hidden design on a hundreds board. Students then create their own problems.
