These are the answers and examples for mental math strategies including the take-away and distance models, how to add/subtract in different bases using the lattice algorithm, standard algorithm, and partial sums algorithm. I drew pictures for many of the problems to represent my work. I completed this work for the course, Mathematics for Elementary Education I.

This is homework for the class, Mathematics for Elementary Education I. These pages show the incorrect and correct usage of the equal sign, number line models, and a correction or example using a sequence of equations. All of these are for mental math strategies. Some portions are answered in cursive handwriting.

This is homework for the course, Mathematics for Elementary Education I. Part of the document is written in cursive, and the book that was used is Mathematics for Elementary and Middle School Teachers by Sybilla Beckmann. In this document, I have written story problems and explained the properties used to solve them including the associative and communitive properties or addition. Different strategies that students often use are shown. I also show adding and subtracting in different bases.

This document includes story problems of different kinds such as: take from, add to, put together, take apart, and compare. I wrote story problems to match the math problems given and drew strip diagrams to correspond.
