Regrouping: Adding and Subtracting Posters

In our math centers, we have been focusing on adding and subtracting two and three digit numbers. To help my kids remember the steps, they reference these posters at our centers.

Since students need different levels of support, counters, number lines, and pictures are used to help students understand the concept. In particular, I found that using a 0-20 number line was very helpful for my students who were having a hard time. The other number lines featured can be useful if you teach students to estimate their answer.

Place Value Centers

What is Place Value:

To teach children the numerical value of a digit in a number, students need visuals, models, and manipulatives to help them understand why the placement of numbers matter.

Visual and Kinesthetic Learning Tips:

To introduce the concept, I start with tens and ones to help my students understand that numbers can be built with place value blocks. I teach them that ten ones (in yellow) equal one ten rod (in green). Students practice creating numbers with the ones, and then the tens and ones.

The board is also extremely helpful when helping students understand how many tens and ones are in a number. Students who are experiencing difficulty could build the number on the board and then easily transfer their results on the paper to help them understand the concept.

Another feature I love about this board is how it is color coded. This becomes useful when I write numbers since I can stay with the original color scheme when writing a number. Although yellow can be hard to read, orange can be used as a substitute if students are experiencing difficulty reading in that color.  Once I write the numbers, I then ask students to tell me the value of each number. This introduction to place value begins at the main teacher table (in my classroom, we have three to four rotating centers throughout our math period).

Greater Than/Less Than: Comparing Numbers

At station two, students practice comparing the value of each digit by comparing numbers. Since some students confuse the greater/than less sign, additional visuals of a gator can help students remember the meaning of the sign (the gator eats the largest number). At this station, students do a variety of activities to practice. One of my favorite includes a ‘roll and make’ game that has students roll the number, make the number, expand, and then compare the number. A free sample of the game is here.

Read and Write

At station 3, students practice reading and writing numbers. Students are taught to not say “and” when reading numbers. They can practice this over and over again with new numbers written by other students at the table. A great resource I love are the write and wipe boards featured below. This is a highly recommended resource when teaching place value!

Spelling Word Practice

Practice makes perfect, especially when it comes to spelling words. Instead of boring repetition drills or using the outdated method of writing something 100 times, there are many activities students can participate in to practice weekly spelling words.

To start, I downloaded a great resource from teacherpayteacher that guides students to trace, write, build, find and use their spelling word in a sentence. Then, I have students use magnetic foam alphabet blocks and dry erase markers to write and build their words three more times during a rotating center.

To reinforce the skills with an adult, my students can then practice writing their words in sand while saying the word and each letter of the word out loud.

For homework, students can choose from a variety of activities that reinforces the words at home. Here are some ideas below:

  • Write the word 3x times using pencil, colored pencil, and crayon
  • Write the words in rainbow colors
  • Write the words in ABC order
  • Write a sentence for each word
  • Write or type a story using all your spelling words
  • Stamp the words
  • Build the words with legos, clay, dough, yarn or pipecleaners
  • String the words together using letter beads
  • Write the words in a verticle pyramid format. For example: l, lo, lov, love
  • Practice building the words using magnetic letter blocks
  • Type spelling words on the computer
  • Spell words in a sand or salt container
  • Trace words on the back of your hand
  • Spell words in shaving cream
  • Trace letters into the air (sky write)
  • Use ABC blocks to spell words (Scrabble)
  • Build words using ABC stickers
  • Use q-tips and paint words
  • Write words in glue and add glitter
  • Use newspaper and magazine to clip letters to build words

We use a spelling notebook to keep track of their progress and their words. All words are individualized so a spelling book helps everyone stay organized. Please feel free to use some of these ideas in your classroom! 🙂 Enjoy!
