Rewrite Numbers
1.NBT.2 Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
1.NBT.2.A1.NBT.2.A 10 can be thought of as a bundle of ten ones — called a "ten."
1.NBT.2.B1.NBT.2.B The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
1.NBT.2.C1.NBT.2.C The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
This number and operations in base ten lesson covers how to rewrite numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students are asked to read the number, represent it in dots if needed, and group the dots into groups of ten. Then, they rewrite the number and interpret it in words.

Compare Two-Digit Numbers Using Symbols
This number and operations in base ten lesson covers how to compare two-digit numbers using symbols. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students are asked to compare each digit of a pair of two-digit numbers, starting at the highest place value. Then, they identify which number is less than, greater than, or equal to, and write the correct symbol.

Determine Ten More or Ten Less Than a Number
This number sense lesson focuses on identifying ten more or ten less than a number. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students read the problem and identify the bold number. Then, they count ten numbers up to find ten more, or count ten numbers down to find ten less. In addition to the lesson, there are six pages of Independent Practice and review with questions modeled after current adaptive testing items.

Compare Two Numbers (No Symbols)
This number sense lesson focuses on comparing two numbers. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students identify two numbers on a number chart. Then, they identify which number is smaller and which number is bigger. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.

Count by Fives
This number sense lesson focuses on counting by fives. The lesson includes research-based strategies and questions that help prepare students for assessments.
