Early Elementary Math Lessons

Elementary


 
Number Theory
• Counting...This WebLesson covers counting to 100 by ones, twos, fives, and tens. It also introduces the hundreds chart.
• The Number Line...Number lines can help us count. We can use number lines to find numbers that are more than zero and less than zero. Number lines can help us find number patterns, and they can help us add and subtract.
• Sorting and Ordering...We can find patterns every day. Look at the shirt you are wearing. Does it have a pattern? What about your pants? Patterns are everywhere.
• Sequences...When we count, we sequence numbers. We put them in order. Sometimes we count by 1s. Sometimes we count in faster ways by 2s, 5, or 10s. This is called skip counting. Skip counting is a pattern. Finding the patterns in numbers helps us count.
• Comparing and Ordering
Addition
• Adding it Up...Students are introduced to addition using pictorial representations, interpret and write addition sentences, and explore different ways to add up or make a number.
• Basic Addition...Students will practice skip counting and explore the patterns. Also, students are introduced to the identity element, adding doubles, and adding by 10.
• One-Digit Addition...Students practice addition facts through 20, one-digit addition facts using a number line, using input/output charts, solve for empty position equations using story or word problems.
• Two-Digit Addition
• Addition with Regrouping...By looking at each place, we can add large numbers together. Every big addition problem is made of simple addition facts.
Subtraction
• Taking it Away
• Basic Subtraction
• One-Digit Subtraction
• Two-Digit Subtraction
• Subtraction with Regrouping...Regrouping is used to subtract large numbers. In other words, we can borrow in order to solve a problem. If there are not enough ones in the ones place, then you can borrow from the tens place. If there are not enough tens in the tens place, you can borrow from the hundreds place.
Place Value
• Models...In this module, we will explore the concept of place value using different models. We will look at pictures that teach us about place value and we will use special toys, called base ten blocks, to make numbers and help us understand place value.
• Converting
Working with Numbers
• Rounding and Estimation
• Properties
Fractions and Decimals
• Parts of a Whole...Fractions are all around us. If you want to share a candy bar with your friend, you break it in half and share. If you want to one piece of pizza, you eat a fraction of the whole. Even sports are broken into fractions. A soccer field has two equal halves. We play basketball in four equal quarters. Look around and see if you can find more items that are fractions!
• Fractions Around Us...Fractions are equal parts of a whole. You use fractions when you cook, with your friends, and with your family.
• Introduction to Decimals...This lesson introduces students to decimal numbers. Students will practice changing fractions into decimals. Students will practice identifying and naming decimals in the tenths, and will be introduced to decimals to the ten-thousandths place.
Geometry
• Basic Shapes...This WebLesson provides an introduction to basic two-dimensional geometric shapes. Students will learn the names of two-dimensional shapes, and they will count sides and compare shapes.
• Advanced Shapes...The objects around you are 3-D shapes. You can find 2-D shapes in the objects. You can see how tall it is, how wide it is and how tall it is.
• Symmetry
• Perimeter
Charts and Graphs
• Spatial Sense...Coordinate grids can help you find points or objects and shapes. The number pairs tell you exactly where to look or where to draw your point or shape.
• Charts...This lesson introduces students to collecting data, using tally charts, and making graphs from the tally charts.
• Bar Graphs...Graphs are used to show us numbers of things. We can use graphs to compare data. Bar graphs use bars to help us learn about the information.
• More Graphs...Graphs can help us understand numbers. We can look at a graph and tell what the favorite animal is, or how many people like certain things. We can show any kind of data on a graph.
Measurement and Time
• Customary Units...This Weblesson introduces students to basic US Customary units of measurement. Students will practice measuring in inches, pounds, and cups, pints, and quarts.
• Metric Units...This Weblesson will introduce students to metric units of measurement. Students will measure length, volume, and weight.
• Tools for Measuring...This lesson will introduce students to basic forms of measurement. Students will learn what tools to use for measuring length and weight. They will also learn about measuring using cups, pints, and quarts.
• About Time...In this module, students learn how to tell time using analog and digital clocks, including the difference between a.m and p.m. Students also learn words related to time telling including “o’clock”, “half”, and “quarter. Students learn the order and names of the months and seasons of the year.
• Telling Time...In this WebLesson, students learn the parts of a clock and how to use the hands and numbers to tell time. Students also learn how to find elapsed time, choose the appropriate unit of time, and name the number of days in each month.
Money
• Making Change...This unit covers naming, counting, and identifying coins such as pennies, nickels, dimes, and quarters.
• Working with Money
