Difference between place value and partitioning rectangles
This week, we have been working on this second grade common core math standard: Partition a rectangle into rows and columns of same-size squares and count to find the total number of them. We also folded paper more times to make more squares! This was some hard folding for some of my kiddos, but they were able to do it. I really emphasized following directions and making a hard crease.
After folding and counting the squares, we glued them in our composition books and I had students write in the number of rows and columns and use sentence frames to tell how many rows, columns, and squares there were in each rectangle. This anchor chart has helped us throughout our unit.
Partition Rectangles Practice Sheets I put together a unit on partitioning rectangles this week and created a few practice sheets, in addition to our class activities. Included in the unit are directions on how to do the folding activity, practice sheets, directions for a class project, and task cards. Describe the shares as halves, thirds, quarters or fourths Recognize that equal shares of identical whole need not have the same shape.
Measure the lengths of objects twice using different units, such as inches and cm. Solve measuring problems involving adding and subtracting within Tell and write the time to the nearest 5 minutes Know the relationships involving time units: seconds, minutes, hours, days, weeks, months, years. Draw a simple picture graph or bar graph to represent data with up to four categories Geometry Identify and name a range of 2D and 3D shapes.
Identify different types of angles and find them on 2D shapes. Recognize and draw shapes with specific attributes: number of angles, sides, faces, corners, etc. Identify the faces of 3D shapes: squares, triangles, hexagons, rectangles.

And each value of every equal partition must display the same behavior as the other. Boundary value analysis Vs. Equivalence partitioning In the below table, we have listed some of the important difference between Boundary value analysis and Equivalence partitioning: S. Equivalence partitioning 1.
It is a technique where we identify the errors at the boundaries of input data to discover those errors in the input center. It is a technique where the input data is divided into partitions of valid and invalid values. Boundary values are those that contain the upper and lower limit of a variable. In this, the inputs to the software or the application are separated into groups expected to show similar behavior. Boundary value analysis is testing the boundaries between partitions.
It allows us to divide a set of test conditions into a partition that should be considered the same. It will help decrease testing time due to a lesser number of test cases from infinite to finite. The Equivalence partitioning will reduce the number of test cases to a finite list of testable test cases covering maximum possibilities. The Equivalence partitioning can be suitable for all the software testing levels such as unit, integration, system.
Sometimes the boundary value analysis is also known as Range Checking. Equivalence partitioning is also known as Equivalence class partitioning. It will remain free to use. This ITP generates a square. Choose a colour or the grey mask. You can then click on individual cells to hide or highlight them in different colours, and by clicking on the box at the left-hand foot of the grid and using the pointers you can hide or highlight rows and columns.
The prime numbers and multiples can also be highlighted.
