This unit covers solving addition and subtraction problems within 100 using part-whole models, solving addition and subtraction problems within 1,000 using comparison models, and solving one- and two-step word problems involving addition and subtraction within 1,000.

Solving Word Problems Addition And Subtraction.

Students will learn to recognize that the line in the vertical algorithm corresponds to the equal sign. They will continue to work on these algorithms in units on length and weight. Students will learn to subtract within 1,000 without regrouping and with regrouping. This unit covers strategies to subtract within 1,000, subtracting without regrouping, subtracting with regrouping, and meaning of sum and difference. Students will view multiple representations of numbers that include number bonds and place value charts to enrich their conceptual understanding of the vertical algorithm as they gain procedural fluency. Students will learn the standard algorithm by extending their knowledge of mental math strategies of addition and subtraction. This unit covers strategies to add within 1,000, adding without regrouping, and adding with regrouping. However, the main goal here is for students to learn new strategies for solving word problems. While numbers are fairly small some students may find them easy. Solving problems with bar modeling are included to help students understand relationships among quantities in word problems and what operations to use to solve these problems. Students will review and learn to add and subtract one- and two-digit numbers from two-digit numbers within 40. This unit reviews and extends student knowledge of subtraction without regrouping to 40, subtraction with regrouping to 40, subtracting within 100 without regrouping, subtracting within 100 with regrouping, solving word problems with numbers to 100, adding up to four 2-digit numbers, mental math of addition and subtraction within 100. Students will see multiple representations of numbers using number words, number bonds, and place value charts. Students will build and extend their knowledge and skills working with two-digit and three-digit numbers. This unit covers 3-digit numbers, comparing 3-digit numbers, and counting within 1,000. The emphasis in this unit is on understanding the concept of repeated addition. Repeated addition is used to prepare students for learning the concept of multiplication, which is also associated with a part-whole model for the given number of equal parts and the number in each part. Students were introduced to the concept of repeated addition in Grade 1. This unit covers odd and even numbers and repeated addition. Making and breaking 10 are foundational skills that support mathematical concepts of place value, standard algorithm and algebraic thinking. Students will review composing and decomposing numbers using number bonds, making or breaking ten, adding to a ten or subtracting from a ten. Students will add and subtract numbers to 20 mentally using the strategies they learned in Grade 1. This unit covers a review of mental math. Students will use number words, number bonds and place value chart to represent numbers in multiple ways.Ģ nd Grade Singapore Math Scope and Sequence The initial lessons in the Singapore Math second grade are both a review and an extension of content covered in the prior grade that includes relating 2-digit number numbers to the place-value concept and 2-digit numbers as tens and ones.

Prior to starting Singapore Math Grade 2, students should already know that numbers have order, view a group of objects as a unit and how to count within 120, add and subtract within 100. Metric measurement of length, customary measurement of length, time, money, representing and interpreting data, and reasoning with shapes.

Review of addition and subtraction within 20, working with equal groups, numbers to 1,000, adding and subtracting within 100, adding within 1,000, subtracting within 1,000, and solving word problems involving addition and subtraction.
