### Description

This two-week lesson plan pack comes with printables, online activities, and digital versions of practice that will help your second graders review what they learned in first grade math. It also includes ready-to-go Google Slideshows so you can demonstrate in a remote classroom environment.

This unit was designed as a beginning-of-the-year review for incoming second-grade students. It addresses these critical focus areas in math for first grade:

· Using a variety of models to develop meaning for addition and subtraction

· Developing strategies to solve problems with these operations.

· Understanding the relationship between addition and subtraction

· Working with addition and subtraction equations

Use methods to add within 100 and subtract multiples of 10

· Comparing whole numbers (to 100) to solve problems.

· Thinking of whole numbers between 10 and 100 in terms of tens and ones

· Understanding the order of the counting numbers and their relative magnitudes

Develop an understanding of measurement

· Measuring length indirectly

· Understanding the concept of iterating

Reason with shapes and their attributes

· Composing and decomposing plane or solid figures

· Recognizing shapes from different perspectives, describing their attributes, comparing and contrasting

Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 - 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Order three objects by length; compare the lengths of two objects indirectly by using a third object.
