# Geoboards! Rows! Columns! Rectangles!

December 1, 2020 | Rebekah Lowe

Right before the break, students were exploring shapes, learning about sides, and discovering more about quadrilaterals and rectangles.

Students were able to use math manipulatives like number cards, square tiles, and geoboards, as well as work on different activities to create rectangles (a shape that has four sides and four right angles).

Second grade students also found out that a square is actually a rectangle, which surprised them and made them really think about what the traits of a rectangle are.

Here are some of the choices that students were able to play during math:

Double Arrays:

Each student picks a number card and colors the number of boxes on the grid paper.  Then, they double the number.  Finally, they write the addition fact that is shown when they double the number.  Students are creating rectangle arrays! Describing Rectangles:

A student will draw a rectangle in the inside flap.  Then they describe the rectangle on the outside flap.  They can give it to a classmate or a teacher to see if they can figure out the rectangle that the student described!  Rectangles on the Geoboard:

Students used rubberbands to make a rectangle on the geoboard.  Then, they drew it on their geoboard paper.  Lastly, they described how many rows and columns their rectangle had!  Rectangle Riddles:

Students also got the chance to work on some rectangle riddles in their math book.

Here is an example: This rectangle has 3 columns and 3 rows.  Can you figure it out?

The second graders had a fun time working on these choices and getting hands-on with their learning.  Ask them which choice they enjoyed the most!
