In this lesson, students use the fewest number of coins to make a given value.
In this lesson, students use different strategies to make $1 or make change from $1.
In this lesson, students recognize the value of coins and count up to find their total value.
This short video and interactive assessment activity is designed to teach second graders about selecting the correct subtraction sentence.
Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity. Then they extrapolate to determine the height the ball would bounce if dropped from much higher heights.
The purpose of this task is to help students articulate their addition strategies and would be most appropriately used once students have a solid understanding of coin values.
In this math video lesson on understanding the language of word problems, students will learn how to use specific words as clues to decide the mathematical operations they'll need to solve a problem. It includes planning, development and evaluation of the lesson by a group of Math specialists. This resource supports English language development for English language learners.
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.
In this lesson, students learn to add multi-digit numbers.
This lesson is for grades 1-2 on math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation. Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.
For this assessment task, students solve a word problem using a drawing and an equation.
In this assessment task, students will solve a word problem using a drawing and an equation.
This is the About the Cluster document written by the NC2ML group who created the instructional frameworks. This is a great resource to read while starting to plan for Second Grade Cluster 2.
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.
In this activity students will use this interactive activtiy to scratch two digit problems with and withuot regrouping. Students will then match the answer from the answer bank to the correct problem they have scratched.
