They learn to find missing addends, and to obtain a sum from three addends. They practice addition and subtraction story problems, and practice math drills. Unit 2 In this unit students learn what digits are and what place value is to three digits. They learn the expanded form of three-digit numbers, and learn to expand numbers. They learn the word form of three-digit numbers, and learn to use a number line. They also learn about counting order, greater than and less than, odd and even numbers, and counting by tens, fives, and twos. Unit 3 In this unit students learn about place value to four digits, expanded form of four-digit numbers, and word form of four-digit numbers. They explore the thousands period in place value, as well as expanded form and word form of the thousands period. They study greater than, less than, and equal to, as well as logical reasoning with organized lists and charts. Unit 4 In this unit students focus on rounding, including rounding to the nearest ten, the nearest hundred, and the nearest thousand. They learn to round three digits to the nearest ten, and to round four digits to the nearest hundred. They learn to round to the given place value, to count by 25's, by 50's, by 100's, and by 1000's. They also explore using benchmarks and practice rounding story problems. Unit 5 In this unit students investigate addition and its properties, including the commutative property and the identity property. They learn to do addition with parentheses, and they explore the associative property. They discuss doing mental sums of tens, hundreds and thousands, and estimating sums of tens, hundreds, and thousands. They study estimating with different place values, they practice story problems with estimating sums, and they learn about adding and estimating sums with compatible numbers. Unit 6 In this unit students study two-digit addition with and without regrouping. They learn about adding three addends with two digits, and then investigate three- and four-digit addition with regrouping. They practice addition with different place values, how to choose the best method for addition, and addition story problems. Unit 7 In this unit students practice mental differences with tens, hundreds, and thousands. They study estimating differences with tens, hundreds, and thousands, and practice with story problems. They learn to subtract compatible numbers, and to estimate differences with compatible numbers. Unit 8 In this unit students explore two-digit subtraction with and without regrouping, as well as three- and four-digit subtraction with regrouping. They learn to check subtraction with addition, to find differences across zeros, and to do subtraction with different place values. They learn to compare differences, they discuss odd or even sums and differences, and they compare exact answers with estimates. They learn to choose the best method for subtraction, and practice subtraction story problems, as well as addition and subtraction story problems. Unit 9 In this unit students investigate clocks and calendars. They learn to read the hour and the half hour, to read the nearest five minutes, and to read to the minute. They learn different ways to say the same time, they practice story problems with clocks, and they learn to read clocks to the second. They explore choosing a.m or p.m., elapsed time with minutes, with hours and minutes, and calculating time passage. They learn to name the months of the year and to read calendars. Unit 10 In this unit students focus on money. They learn to count pennies, nickels, dimes, quarters, and half-dollars. They learn to count bills and coins, and to compare money amounts. They practice money story problems, and learn to add and subtract money, and practice with more story problems. They celebrate the number 100, and learn to calculate and count change. Unit 11 In this unit students learn about statistics. They investigate tally and frequency tables, pictographs, bar graphs, and line plots. They learn about mode and range. They discuss line graphs, circle graphs, and ordered pairs. They study probability of events, predicting outcomes, and fair versus unfair games. Following this unit students are presented with the Mid-Term Review and Exam. Unit 12 In this unit students delve into multiplication.

Unit 14 In this unit students investigate division. They learn to understand division and learn multiplication and division fact families. They learn to divide by one, two, three, four, five, and ten. They learn division rules for zero, and learn more division facts. Unit 15 In this unit students begin with division story problems, including story problems where they are required to choose the operation, as well as story problems where they are required to work backwards. They learn about equations and expressions, about finding the missing operation, about using order of operations, and about doing calculator division. Unit 16 In this unit students explore geometry. They explore lines and angles, learn geometry terms, and learn to describe angles and lines. They learn to identify polygons, and to classify triangles by anlges, as well as to classify quadrilaterals. They study circles, congruent figures, and finding lines of symmetry. They learn to identify solid figures, and to relate objects to solid figures. Unit 17 In this unit students study fractions. They gain understanding of fractions as part of a whole and as part of a group. They learn to find a fraction of an amount, and to understand equivalent fractions.
