This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials The Very Hungry Caterpillar by Eric Carle The students work individually or in pairs. Each student or pair needs: Three ten-frames for each s...

This parent guide supports parents in helping their child at home with the 1st Grade Math content.

This resource accompanies our Rethink 1st Grade Math Operations and Algebraic Thinking 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 in Operations and Algebraic Thinking.

In this Khan Academy interactive, students will solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20.

With this interactive, students are given a word problem to solve by adding three numbers. They type in their answer and click Check to see if their answer is correct.

This interactive resource defines the term "Bridging to Ten", and contains an interactive to illustrate the definition. Students use the place value visuals to illustrate bridging to ten, practicing building up to ten or building down to ten to more easily add two numbers.

For this assessment, students help Mike determine which cards to pick to get close to 20, then explain their reasoning.

This site is a series of video lectures and interactive exercises for teaching basic mathematics skills to first graders. It has separate addition and subtraction skills reviews numbers up to 10, 20, and 100; a section on telling time and reading clocks as well as course material on measurement and geometry.

For this assessment, students decide which groups of fruits should be picked to make a fruit salad consisting of 15 fruits.

For this assessment, students decide how many studetns might be eating certain fruits based on a a total number of fruits being eaten.

Students solve addition and subtraction problems to 20 by counting all the objects in their head.
