Ten Less - Subtract 10

My students still need opportunities to practice subtracting ten from a 2 digit number. I have put together a couple of worksheets and a game to help students with this skill. Some students needed to use a hundred's chart (included) to help them. Other students were more strategic. When they rolled a 5 and 1 they could make 15 and then subtract 10 to get 5 or they could make the number 51 and subtract 10 to get 41. Love games that incorporate both skill and strategy work!

More Place Value - Ten More Game

We are winding down our place value unit. I am a firm believer in giving students multiple opportunities to practice a skill.. While worksheets have a place, I prefer to use games to reinforce math skills; it also is a great way to build fluency/automaticity. Here are some simple games to practice ten more. All you need is the game board, dice, and a partner. For first graders that can already add ten more to a number, use the last game board with 3 dice (for more of a challenge use number cubes) and encourage them to organize the cubes in a way to add the numbers more efficiently.     Click Here for a free copy.

Place Value - Ten More and Ten Less

My students are amazing. They are making such great progress in math. As part of my place value unit, I'm working on the concept of one more and one less. We played a variation of a game I have seen in many forms. Each child had a hundred's chart, one game piece (I used bears), and a spinner card. Students put their game pieces on number one to start. On each turn, the child would spin and either add or subtract 1 or 10. If the child couln't subtract the number he or she would lose a turn.

To assist some students, I had them count by using a finger to point to each number on the hundred's chart. Doing this before moving the game piece helped. Other students didn't need to do this. I loved seeing the Aha! moment when some realized how easy it was to add 10. I was thrilled when one commented, "Oh, you just add one to the ten's place." Others aren't there yet, but getting close.

First Grade Place Value Websites

Three days a week, I do my version of math workshop. In one center, students use the computer to reinforce the standards covered. I create a word/html document and put it in a shared folder so students can just click on the links (actually I embed the link in  a picture from the website).  Email me and I'll send you a copy of this.Sometimes I use these when we go to the computer lab.

I have included a brief description so that you don't have to research these yourself. I tend to avoid sites that have ads or are too busy.

First Grade – My Favorite Hundred’s Chart Interactive Websites

This is great to do with an interactive whiteboard (or have students do it on their own). Students will race to find numbers on a blank hundred’s chart. I line six to eight students up at a time and then they quickly find “the number” and sit down. A great way to learn to visualize numbers on a 100’s chart.
This is an interactive hundred’s chart which allows students to paint different numbers. This is just an exploration type activity. 
Find the target number on a hundred’s chart. 
Find 10 more than the target number on a hundred’s chart. 


My Favorite First Grade Place Value Websites

You are given the tens and ones, and you need to find the numeral that matches. If you are correct, the dolphin jumps over the boat, incorrect a shark takes a bit out of the boat.
Shark Numbers - More shark fun. Select one of 4 levels with the highest being numbers up to 999.
Shark Pool – Ten’s and One’s
The same as shark numbers but with cups instead of place value blocks.
A funky drum rhythm plays as you use base ten blocks to form numbers. You can select one’s and ten’s or add the hundred’s place.
Ten’s and one’s using ten frames, not much pizzazz to this site, but great for visualizing tens and ones using 10-frames.  You can also use this whole group or with an interactive white board while students record this on a whiteboard or place value mat.
Dinosaur Place Value – Build numbers by clicking on the correct dinosaur eggs. For the number 15 you will need to click on the 10 and 5 eggs. Cool dinosaur roaring.
Given tens and ones, identify the number.
Identify the digit in the ones, tens, or hundreds place
Save the swimmer by using a number line and a ten’s and one’s button on the lifeguards boat.
Critter Junction - This site goes to the hundred’s place. Feed the critters. Add place value blocks for hundred’s, ten’s, and one’s.

Place Value

I'm always trying to find or make up games that have my students practicing math skills. The ideal games are ones that don't require a lot of prep time but reinforce a needed skill. I want my students to be adding, counting, and making groups of ten, so I decided to use unifix cubes and dice (I have tons of different types of dice) for this activity. I have included different recording sheets.
