Number Sense Activities

Here are some fun number sense activities that we have been doing in 1st grade a la Sarti.

Rock, Paper, Scissors, Math - this game has many variations but we start by using one hand to show a number (instead of the rock, paper or scissors), then the partner has to name the other person's number and vice versa. We say "your number is __". "Your number is __". "Your number is more". "Your number is less". You can use 2 hands to show numbers through 10 or have the students add the numbers and the first one who name the sum wins. We play this every day after calendar.

Number Necklaces (musical share)- I make number necklaces with the number and number word (#s 0-20 at first) and the representation on the back. I'll turn on music and they walk around until the music stops, then they find a partner and read their number. Like R,P,S,Math, they decide who is more/less etc, count up to the number, count back from the number, name the number before/after and so on. I also have them line up in number order without talking, only viewing the number on others necklaces. Eventually we will sort by number patterns, odd/even, before/between/after, the possibilities are endless! (I got the number necklace/musical share idea from my team mate Ruth, she is genius!)

 

Ten Frame - students need to understand that numbers are more than symbols, we use the ten frames to represent the numbers and eventually transfer this into place value. We use ten frame mats and counters and I provide the number for the students to build. 

For independent practice I use the ten frame printable from the teacher resource guide and either write a number and have them draw to build or draw the circles and have them write the corresponding number. I also let them select their own number by rolling dice or choosing an number magnet from the tub. They then write the number and draw the representation. I love using manipulatives for hands on learning!




 What are some of your number sense activities?
