VIDEO 3 OF 3 - This video addresses NC standard 5.NF.1. It explains how to connect the use of models for addition/subtraction of fractions to the standard algorithm for adding/subtracting fractions.

Students will soon figure out algorithms are part of the many things they do everyday from planning their day, working on a project to writing code. An algorithm is a detailed step-by-step instruction set or formula for solving a problem or completing a task.

Building on the programming basics learned so far in the unit, students next learn how to program using sensors rather than by specifying exact durations. They start with an examination of algorithms and move to an understanding of conditional commands (until, then), which require the use of wait blocks. Working with the LEGO MINDSTORMS(TM) NXT robots and software, they learn about wait blocks and how to use them in conjunction with move blocks set with unlimited duration. To help with comprehension and prepare them for the associated activity programming challenges, volunteer students act out a maze demo and student groups conclude by programming LEGO robots to navigate a simple maze using wait block programming. A PowerPoint® presentation, a worksheet and pre/post quizzes are provided.

Using new knowledge acquired in the associated lesson, students program LEGO MINDSTORMS(TM) NXT robots to go through a maze using movement blocks. The maze is created on the classroom floor with cardboard boxes as its walls. Student pairs follow the steps of the engineering design process to brainstorm, design and test programs to success. Through this activity, students understand how to create and test a basic program. A PowerPoint® presentation, pre/post quizzes and worksheet are provided.

This lesson is from Tools for NC Teachers. In this lesson, students apply their knowledge of place value to add whole numbers while exploring the standard algorithm. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students apply their knowledge of place value to subtract whole numbers using the standard algorithm.

These documents are from Tools4NCTeachers. These provide details about the multiplication and division algorithms and how other strategies connect to algorithms.

This lesson is from Tools4NCTeachers. In this lesson, students develop and implement strategies for solving multi-digit multiplication problems. Students will solve the problems in at least two different ways and explain their reasoning. This lesson should be an introductory lesson to multiplication of multi-digit numbers. This is remixable.

This task is from Tools 4 NC Teachers. Students explore a division problem with remainders. This is remixable.

Students will learn about algorithms and how to create and follow step-by-step instructions when going through the code.org lessons.
