Place Value

The Common Core Place Value standards are so important when teaching first and second graders. Understanding the meaning of ones, tens, and hundreds sets the foundation for counting, adding, and subtracting. When I teach place value, I emphasize the use of manipulatives with my students. I especially have success using place value blocks. I like place value blocks because students can see that a ten is composed of ten ones and a hundred is composed of one hundred ones.Place value blocks are also easy to manipulate.

My students love Mr. R's Place Value Song! You can watch it here or on You Tube.
He also has a TpT Store!

In the beginning of the year, I like to reinforce place value with my students by doing a Number of the Day for morning work. The routine and repetition of Number of the Day really helps students gain number sense. You can use a printed sheet for number of the day, but if your copies are limited, this Rainbow Number of the Day worked great for my class.

I just created this poster and had students fill in each section with the corresponding color in their Number of the Day Journal. In the beginning of the year, we went over the Number of the Day as a class. As students mastered this concept, I took a few minutes to check student journals and pull small groups as needed.

My students also loved making a Place Value Book. 

The book, along with other worksheets, a scoot game, and a quiz can be found in my first and second grade place value packet on TpT. 



Teaching Arrays in Second Grade

Partitioning Rectangles (2.G.A.2) and Arrays (2.OA.C.4)

These standards go together perfectly because they both involve arrays. 2.G.A.2 asks students to partition rectangles into rows and columns to make arrays. Standard 2.OA.C.4 asks students to use addition to find the total number of objects in an array. 

This is my favorite 2nd grade math unit because arrays work perfectly with using food! These lessons are very engaging and memorable for students. Here are some ideas I have used in the classroom:


After students have some familiarity with these standards, I bring in a tray of brownies. I ask students to help me figure out how I should cut the brownies into rows and columns so we have enough brownies for everyone in the class. I give students time to make a plan in groups. After students come up with a solution, they share with the group. When we find a plan that will work, we cut the brownies and enjoy!

Chocolate Bar Math

This is always my second grader's favorite lesson. In this lesson, I bring in a chocolate bar (divided into rectangles) for each of my groups. Students complete an activity with their team using the chocolate bar. Of course, the best part is when students get to partition the chocolate bar and eat it in the end. This lesson can be found, along with other practice sheets for these standards, here:


Open House

Back to school means getting ready for open house. Here are some forms you can use to stay organized. Click on the pictures to grab them for free!


I hate to lecture parents on open house night. Often parents get bored and it makes me nervous! When I was in the classroom, I liked to create a short PowerPoint presentation with key things parents want to know. I created this template to make creating your own presentation easy. Grab it here for free:

In my school students were always invited to join their parents at open house. When I was in the classroom, I liked to include the children in the night. Students always are so excited to show their parents the classroom, so I created these scavenger hunts. This activity has always been a big hit! It also gives parents the chance to see what goes on in our classroom. Snag them for free here:

I hope your open house night goes smoothly!
