Exercise Algorithm! - Fun, FREE, Technology Worksheet, Activity and Presentation
A fun, engaging activity teaching students about ALGORITHMS. Included is a 6 slide PowerPoint presentation and a fun activity in which students create their own exercise algorithm. You can then direct students to follow each other's algorithms. If you are wondering what an algorithm is... it's is a set of step-by-step instructions that can be followed in order to solve a problem. This resource is part of a 5 lesson computational thinking unit for younger students - perhaps in Kindergarten, Grad

Box and Whisker Plot Algorithm for student use desk copy.
This is a step-by-step algorithm for creating a box and whisker plot. It is intended for student use and can be copied and laminated for them to keep and use as a reference tool. There are four of each one on a page for duplication purposes, but a single one can be copied and pasted for a whole classroom or sign use.

Partial Products Multiplication with Standard Algorithm
This is a great way to show partial product multiplication and standard algorithm multiplication. This works great in a sheet protector and using it as a white board template! Works best in small group instruction, but can be used whole group as an informal assessment!

PROBLEM SOLVING
This activity is practice for the traditional algorithm method by using a problem to solve in the classroom. I have students in groups and have them rotate to the stations around the classroom.
The first page is for students who are fast learners and really know their multiplication tables. The second page is for learners who are still working on their multiplication and understanding of adding and subtraction.

Two Digit by Two Digit Multiplication Worksheet
This is a 20 question worksheet.
Questions 1-10 are meant to be solved using expanded algorithm (arrays, area models and place value charts are suggested in the directions)
Questions 11-20 are all two digit numbers multiplied by multiples of ten. These are meant to be solved using the shortcut method.
I use this worksheet as a review for these strategies before teaching my fourth graders standard algorithm.

BOX METHOD MULTIPLICATION GRAPHIC ORGANIZER
Students can use this pre-formatted graphic organizer to solve BOX METHOD multiplication. Students who have difficulty solving multi-digit multiplication problems using the standard algorithm can use these organizers to help them organize partial products as they multiply 2 and 3 digit factors.
Because the box method uses base 10 strategies, it is sometimes and easier method since it involves multiples of 10, 100, and 1,000. Taking a challenging computational product and breaking it down
