4434Motion Math Educator Suite
https://www.merlot.org/merlot/viewMaterial.htm?id=1113860
This suite of 6 games covers elementary math skills from addition & subtraction to multiplication & division, to fractions and decimals. My students’ current favorite is Motion Math Pizza, where they build and sell pizzas to hungry customers, setting the prices and seeing how basic economic principles work.Tue, 29 Dec 2015 15:20:15 -0800Interactive Newton's Method Visualization
https://www.merlot.org/merlot/viewMaterial.htm?id=1083438
This is an interactive activity where you can type in any function and have the computer use Newton's Method to find the root. It animates the tangent line being drawn to the x-axis, then back up to the curve and the draws the next tangent line. It also shows the guess at each iteration of Newton's Method.Fri, 27 Nov 2015 11:21:43 -0800Touch Integers ℤ (+ - × ÷)
https://www.merlot.org/merlot/viewMaterial.htm?id=1078248
Is very easy add and subtract graphically. One can regroup the tokens of each order, regroup, carry or borrow tokens, and you can obtain the resultBut not so easy to practice multiplication or division in this visual and interactive wayI looked the inside of the numbers:Inside the numbers there are the components of the number: The prime factors.To multiplicate two integers you must regroup the components of the two numbers.To divide a integer, you must separate the components.The program only works with integers. adds, subtract, multiplies and divides (but only exact division)Wed, 11 Nov 2015 03:22:20 -0800Math Playground Games

https://www.merlot.org/merlot/viewMaterial.htm?id=1041297
Touch decimals Place value ±Double interactive place value chart.Wireless abacus.- Show and experience the addition and addition with carry.- Show and experience the subtraction and subtraction with borrowing.- Zero as "nothing" in a place value place, or as negative-positive pairs of Tokeens or Places with sign.Two configurations: Default and J. LeMieux version:Change the version, upper back arrow, or at the menu option.D E F A U L T C O N F I G U R A T I O N :(Positive and negative Tokens, and Places without sign)MAIN ELEMENTS:Each chart with a variable number of places.In the places, a variable number of tokens with positive or negative valueTOKENS:A token can be positive or negative.A positive token is born with the tap of a finger on the screenA pair of positive-negative tokens is born with a tap of two fingers on the screenA token disappears if it crosses the top or bottom border.The behavior of tokens:Positive and negative tokens have the same behavior:A token can cross at will the intermediate horizontal borderWhen a token crosses the border on the right, it becomes 10 tokens.A token need 9 companions from the old place to cross the border to the left.Positive and negative tokens may be in the same place. But if two tokens of different signs meet, they cancel each other.PLACES:A place can contain tokens of the same or different sign.The upper and the lower borders can be the external border or the intermediate border.Tokens can cross freely the intermediate border.If a token cross the external border, disappears. To get the permission to cross left borders, a token needs 9 companions of the same sign.A token recovers 9 companions if cross the right borders.GENERAL:There are two charts: The upper chart and the lower chart.There is a button in each chart to change the sign of all its tokens.L E . M I E U X C O N F I G U R A T I O N :(colored Tokens without sign, and Places with sign)MAIN ELEMENTS:All the Places of each chart can be positive or negative.TOKENS:A pair of tokens is born with a tap of two fingers on the screen over two places of different sign.The behavior of tokens:A token can cross at will the intermediate horizontal border if the places have the same sign.When a Token tries to cross the border to a Place of a different sign, calls another Token of the other Place, and they cancel each other in the border.PLACES:A place can contain not signed colored tokens.Tokens can cross freely the intermediate border if the sign of the two places are the same.GENERAL:There is a button in each chart to change the sign of all its Places.In the 'settings' option, there is an option to erase all tokens of each chart, or to erase all tokens and refresh all to start again from scratch.The behavior of places and tokens of this app describes the behavior of the numbers in the decimal system.Courses:Math 1, 2, 3, 4 Number sense: Place value.Math 5, 6, 7 Base Ten:Common Core:CCSS.MATH.CONTENT.1.NBT.B.2; CCSS.MATH.CONTENT.1.NBT.C.4; CCSS.MATH.CONTENT.1.NBT.C.5; CCSS.MATH.CONTENT.1.NBT.C.6; CCSS.MATH.CONTENT.2.NBT.A.1; CCSS.MATH.CONTENT.2.NBT.B.5; CCSS.MATH.CONTENT.2.NBT.B.6; CCSS.MATH.CONTENT.2.NBT.B.7; CCSS.MATH.CONTENT.2.NBT.B.9;CCSS.MATH.CONTENT.3.NBT.A.2; CCSS.MATH.CONTENT.3.NBT.A.3;CCSS.MATH.CONTENT.4.NBT.B.4; Developed by: http://www.nummolt.comNummolt Blog: Mathematical engine mill: http://nummolt.blogspot.com.es/2015/07/touch-decimals-chapter-i-introduction.html Sat, 27 Jun 2015 06:05:47 -0700Graph.tk
https://www.merlot.org/merlot/viewMaterial.htm?id=1039751
Graph.tk is an online and open-source graphing utility.It's very easy to use. Use the "+" button to create a new equation. Use "/" for fractions, "^" for exponentials, and "*" for multiplication. No install necessary. Runs straight from within the browser using the new HTML5 features. But it can still save all the graphs, and it still works when you're not even connected to the net! You will just need to have a good modern browser (Firefox 4+, Google Chrome 14+, Internet Explorer 9+, Opera 11.60+, Safari 5+).Tue, 23 Jun 2015 10:16:43 -0700Scientific Calculator

Scientific Calulator is a powerful, programmable, scientific calculator.Some of its features include: Supports variables, constants, and custom functions; Save scripts online so you can access them anywhere or in a local library; Complex numbers, arbitrary precision integers, and exact fractions; Algebraic pretty-printed display; Full functional programming language; Supports matrix and vector operations; Calculation history lets you refer to previous results.Tue, 23 Jun 2015 10:10:23 -0700Spousal Heights Applet
https://www.merlot.org/merlot/viewMaterial.htm?id=1037910
Students record the heights of male and female spouses. Students then use Excel to test for a correlation in heights of married couples. Used for an activity on correlation analysis.This applet was developed as part of a first course on biostatistics. It is used as part of a series of online lab activties for that course.Thu, 18 Jun 2015 11:23:14 -0700Leaf Photosynthesis Applet
https://www.merlot.org/merlot/viewMaterial.htm?id=1037920
Students record the rates of photosynthesis for leaves under different light intensities. Students then use Excel to fit a line to predict and evaluate photosynthetic rate as a linear function of light intensity. Used for an activity on linear regression analysis.This applet was developed as part of a first course on biostatistics. It is used as part of a series of online lab activties for that course.Thu, 18 Jun 2015 11:18:15 -0700Pupa Weight Applet
https://www.merlot.org/merlot/viewMaterial.htm?id=1037918
Students randomly sample male and female flour beetle pupa grown on three types of media and record the weight and sex of each insect. Students then use Excel to test for effects on mean weight due to type of media, sex, and the interaction between these two factors. Used for an activity on two factor analysis of variance (ANOVA).This applet was developed as part of a first course on biostatistics. It is used as part of a series of online lab activties for that course.Thu, 18 Jun 2015 11:11:54 -0700
