# Early math

Math begins with counting. It's the most important skill we learn in our early years and becomes the foundation for all other math concepts. Once we can count, we can add, subtract, and measure the world around us. Shortly thereafter, we can learn about place values, plots, graphs, time, money, and shapes. These early math skills are presented in this subject's tutorials in a straightforward, understandable, and (dare we say it) fun way!

# Measurement and data

Is a bat longer than a hot dog? How much money is in your wallet? Let's find out. In this topic, we measure objects and compare their measurements. We also create picture graphs, bar graphs, and line plots and use the graphs to answer questions. We tell time with analog clocks. And finally, we count U.S. coins and dollars.

## Measurement

Discover how to measure length. Then estimate lengths, measure objects using various units, and compare measurements. Finally, put it all together to solve measurement word problems.

## Data

Read and interpret line plots, bar graphs, and picture graphs. Then, make some of your own!

## Time and money

Tell time using analog clocks. Find the total value of U.S. coins and dollars.
