Number Sense and Place Value: Students will develop an understanding of place value through 100s. Students will learn to compare values of up to three digit numbers. Students will develop fluency with adding and subtracting within 20.
The students will use strategies and models to solve two digit addition and subtraction problems with and without regrouping within 100. They will also apply these strategies and models when solving one-step word problems with unknowns in all positions.
In this unit the students will learn to represent and solve three digit addition and subtraction problems within 1,000. Students will recognize when it is necessary to compose or decompose tens or hundreds. They will apply their understanding of the relationship between addition and subtraction to solve two-step word problems.
In this unit students will learn about two-dimensional shapes, time and money. They will learn to describe and classify shapes as polygons or non-polygons. They will decompose and combine shapes to make other shapes and they analyze two-dimensional shapes to develop a foundation for understanding area, congruence, similarity, and fractions in later grades. Students will work to solve problems involving money up to $1 including counting mixed coins and making change. They will identify all coins and be able to arrange them in order from greatest to least value. Students will also be able to tell time using both analog and digital clocks to the nearest 5 minute and identify a.m. and p.m.
In this unit students will learn to recognize the need for standard units of measure (centimeter and inch) and apply this understanding to addition and subtraction problems involving length. The students will learn to recognize that the smaller the unit, the more iterations needed to cover a given length and they will learn to select appropriate tools to measure understanding that linear measure involves an iteration of units. The students will also learn to interpret and represent data in multiple ways, such as: line plot, bar graph, picture graph, and a tally chart.
