This short video and interactive assessment activity is designed to teach fourth graders about addition: completing the addition sentence.
This Math Center is great for using in Rotation Math in Early Elementary. Students can work independently and are engaged at this addition center.
The purpose of this task is to study some patterns in a small addition table. Each pattern identified persists for a larger table and if more time is available for this activity students should be encouraged to explore these patterns in larger tables.
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 aspects of the task and its potential use.
This document contains 6 posters full of good addition strategies to use with students.
This document is the planning template for Triads when examining student programming and classroom supports.
Students place markers on the numbers 2-12. Students toss two 6-sided dice, find the sum and remove a marker from that number, if there is still one. The first player to remove all markers wins the game. This game can be used as addition practice or as an introduction to the probability of the different outcomes of rolling two dice. This game was developed by a Monmouth University student for the Probability Fair. These games help students acquire proficiency in addition and subtraction facts.
Learn addition and subtraction.
This short video and interactive assessment activity is designed to teach third graders about one step addition and subtraction - word problems.
This short video and interactive assessment activity is designed to teach fourth graders about one step metric capacity with addition and subtraction - word problems.
This short video and interactive assessment activity is designed to teach fourth graders about addition of capacities - word problems.
This short video and interactive assessment activity is designed to teach third graders about addition of sequential capacities - word problems.
The first in a two-part series, this Module discusses problem behavior in terms of the stages of the acting-out cycle and suggests ways to respond to students in the cycle's different phases (est. completion time: 1 hour). When you have completed this Module, be sure to learn more in part two.
The second in a two-part series, this Module describes interventions that can increase initial compliance to teacher requests as well as interventions that can be implemented to decrease disruptive and noncompliant behaviors.
As emissions of heat-trapping bases accumulate in our atmosphere, Earth's polar regions are warming more quickly than at lower latitudes. The rapid environmental changes that result from this warming can have a significant impact on the physical and mental health of rural Alaskans: unpredictable weather and changes in the seasons have made harvesting food more difficult, hazardous, and stressful. The risk of physical injury has also increased, as poor ice, extreme weather, and coastal erosion bring new travel hazards. Increasingly difficult harvest conditions for fish, shellfish, berries, caribou, and sea mammals have also increased concerns about food security. Additionally, declines in snow pack, the threat of drought, changes in lake and river conditions, and damage and disruptions to community water systems have prompted concerns of water security. The climate-related challenge faced by Alaskas tribal health system is to recognize new health stressors and community vulnerabilities, and then find healthy adaptation strategies in an increasingly uncertain future.
In 2012, water managers in Fredericktown, Missouri, saw their city's main source of water dwindle. They used the EPAs Climate Ready Water Utilities program to consider options and develop plans to protect their water source.
This course features a video review of addition up to the sum of ten for first graders.
This short video and interactive assessment activity is designed to teach second graders an overview of addition (sums to 10).
This short video and interactive assessment activity is designed to teach second graders an overview of addition.
An interactive applet and associated web page that show the concept of adjacent angles (two angles that share a common leg). The applet shows three line segments with a common endpoint. The user can move the center one and see that the angles on both sides (the adjacent angles) of it are affected. Applet can be enlarged to full screen size for use with a classroom projector. After use in the classroom, students can access it again from any web browser at home or in the library with no login required. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
