Unit 1In the first unit of the course, students will begin by reviewing and building on their addition skills. Following this, they will be introduced to other useful tools, such as math tiles and number lines. The unit will close by discovering doubles and near doubles facts.Unit 2Unit 2 continues the student’s work with addition. First, they will explore adding onto tens and making tens. Next, they will investigate adding with zeroes and changing the order of addends. The students will complete the unit by examining word problems and adding three numbers at once.Unit 3This unit dives into subtraction. Students will begin with a review on subtracting problems using a model. Following this, they will explore word problems and number lines using subtraction.Unit 4Unit 4 combines exercises in addition and subtraction using part-part-whole diagrams. They will practice relating addition and subtraction facts to solve for the answer. Next, students will learn to identify missing parts of problems, such as addends and the missing whole. They will close the unit by exploring addition and subtraction using number lines.Unit 5This unit explores the way numbers are written or worded. It begins by identifying tens and how to figure and write numbers using ones and tens. Next, students will examine place values and expanded forms. They will conclude the unit by counting to 100 and learning the different ways to write numbers.Unit 6Unit 6 begins by exploring the concepts of less than, greater than, and equal to. Following this, students will investigate odd and even numbers and will complete the unit by learning to count by fives, and tens.Unit 7This unit explores setting up and adding two-digit numbers. Students begin with regrouping, modeling, and recording. They will follow that up with practice of two-digit addition. Finally, they will investigate rewriting two-digit problems and solving them.Unit 8Unit 8 begins with students learning how to add by tens in their minds and how to round to the nearest ten. Next, they will practice with two-digit addition with sums that are larger than 100 before progressing to adding three and four two-digit numbers at a time.Unit 9This unit is similar to unit 7, only using subtraction. Students start with regrouping, modeling, and recording two-digit subtraction. They will complete the unit by rewriting and solving two-digit subtraction problems.Unit 10Unit 10 dives deeper into two-digit subtraction. Students begin with exercises in subtracting two-digit numbers. Next, they will explore the application of two-digit subtraction and then they will finish the unit by learning to check their problems by using addition.Unit 11This unit begins by showing students how to subtract tens mentally and practicing two-digit addition and subtraction. Next, they will explore using addition and subtraction to solve real world situations and will close the unit by investigating subtraction with two subtrahends.Unit 12In the last unit before the midterm, students will explore graphs and surveys. They will examine surveys, bar graphs, pictographs, and line plots. They will conclude the unit by discovering how to use graphs in science.Unit 13This unit explores money and how to count it. It begins by showing students how to count pennies, nickels, and dimes before a lesson in their value. Next, they will discover half dollars and quarters and how to count them. Finally, they will examine full dollars and then combining them with coins.Unit 14This unit helps students investigate the importance of saving money, as well as withdrawals and deposits. Following this, they will examine responsible borrowing and lending decisions. Next, students will practice counting money and then will learn to solve money word problems. Finally, they will explore money symbols and the cost of making things.Unit 15Unit 15 explores the different ways of telling time. Students begin by examining minutes and hours, followed by telling time to fifteen minutes and then five minutes. To conclude, they will discover the difference between A.M. and P.M. and how to tell time to the nearest minute.Unit 16This unit has students investigating plane and solid figures. They will begin by identifying plane figures and then examining their sides and vertices, as well as combing and separating them. Finally, students will study solid figures, how to combine them, and their relationship to plane figures.Unit 17This unit introduces the students to standard and metric measurements. They will explore inches, feet, yards, and miles, followed by centimeters and meters. They will complete the unit by measuring the length of objects using different units.Unit 18Unit 18 further explores measurement. Students begin by examining how to use measuring tapes and comparing lengths of various items. Next, they will be introduced to word problems concerning length. Finally, they will discover the relationship between length and line plots and will conclude the unit by exploring area.Unit 19This unit introduces students to fractions. They will compare fractions before examining numerators and denominators. To conclude the unit, they will investigate fractions that describe one whole and fractions that are greater than one whole.Unit 20This unit explore the difference between ones, tens, hundreds, and thousands. Furthermore, students will study number words that go to 1,000, as well as the expanded form of three-digit numbers. They will close the unit by comparing numbers to 1,200.Unit 21Unit 21 begins with skip-counting by hundreds and adding hundreds mentally. Next, students will study regrouping ones in three-digit addition, followed by regrouping tens in three-digit addition. Finally, they will be given three-digit addition problems to complete.Unit 22In this unit, students will first be presented with subtracting hundreds. Following this, they will study regrouping tens and hundreds in three-digit subtraction, as well as practice problems using three-digit addition and subtraction. Students will close the unit by examining and solving multi-step word problems.Unit 23In the last unit of the course, students will explore skip counting by threes, fours, sixes, sevens, eights, and nines, as well as using skip counting to find totals. Next, they will investigate the relationship between addition and multiplication and will finish the course with a small introduction to division.
