After teaching the standard algorithm for so many years, I've found that my students can not identify the mistake in the math problem that they had made. I made this power point to have students evaluate a problem and find the error so they may be better equipped to identify their mistakes. When we complete this power point, we play it as a game. I group the students, show them a problem and the first group to find the problem hits the bell. They then have to go to the board and show the cla

This Power Point walks through using the distributive property to solve 2 digit by 1 digit and 3 digit by 1 digit multiplication problems. With each mouse click, the next step in the process is revealed. There are 4 slides which demonstrate the process using arrays. The four examples with arrays are all 2 digits multiplied by 1 digit. There are four more 2 digit by 1 digit slides that illustrate the process without an array. There are three slides that illustrate 3 digit by 1 digit problems. Alo

This Power Point gives step by step instructions on identifying and solving additive and multiplicative comparison problems. The first two slides give two word problems. Students are to identify the key words and with a mouse click, the key words are highlighted. With each click of the mouse, the problem is worked out. Slides 4-9 give a single word problem in which students identify the key words and solve. In addition to the slide show, an activity is provided so that students may practice writ

This power point is a follow up to my "Multiplying Using the Distributive Property" powerpoint (students multiply 2 and 3 digit numbers by 1 number) which is also on TPT. In this power point, students will walk through the steps of using the distributive property to solve 2 digit by 2 digit problems. A click of the mouse reveals the next step in the process. A power point guide is provided and students are able to complete the problem on their guide as the power point is played. The first 4 slid

This power point takes the kids through the process of comparing fractions over a two day period. Comparing first with like numerators, then like denominators then by cross multiplication. I've included a slide breakdown so that you can follow my train of thought. I've also included the greater than, less than and equal to signs that I print on cardstock and laminate and use throughout the year. CCS: MA.4.M.4.6

To practice rounding numbers, I made this game. Students select a card, round the underlined digit on the card, partners check their answer, and if correct students move around the gameboard. After the whole class plays, I put it in one of my math centers.

Division unit vocabulary cards include the terms difference, division, divisor, dividend, quotient, and division notations. The cards also include how to tell if a number is divisible by 2, 3, 5, 6, 9, and 10 with examples. Printing the cards for the students saves time and prevents handwriting and copying issues. Look great in black and white too!

This power point is used to introduce fractions. I've taken the lesson and broken it into 3 sections. The first section defines fractions, identifies the numerator and denominator, describes the function of the numerator, and the function of the denominator. In the second section, students identify the numerator or denominator of fractions and students create fraction stories that coincide with a picture on the slide. I've added this to the lesson this year since my district is focusing on s

In this game, students will practice using the divisibility rules. When students land on a number on the game board, they must decide, by using the divisibility rules, whether that number is divisible by the number they spun on the spinner. If yes, they collect divisibility dollars. The person with the most divisibility dollars wins! You can spice up this activity by allowing students to buy prizes with the dollars they have won!

This power point covers the steps to multiplying 2 digit whole numbers by 2 digit whole numbers using the rectangular section strategy. With each mouse click, the next step in the process is revealed. A power point guide is provided so students can fill in the answers as you work the power point. The first 4 slides give step by step directions and the last 4 have multiplication problems the students can solve on their guide sheet. I have a smart board so the students solve, then get called t

To practice identifying value, I made this game. Students select a card, identify the value of a digit in a number, partners check their answer, and if correct students move around the gameboard. After the whole class plays, I put it in one of my math centers.

To practice identifying place value, I made this game. Students select a card, identify the place value, partners check their answer, and if correct students move around the gameboard. After the whole class plays, I put it in one of my math centers.
