Numbers, Numbers, Numbers

We have been focusing on Number Sense and Numeration in our classroom.  The Educators have provided many different learning opportunities for students to subitize (recognize an arrangement of dots or objects without counting), add numbers together, and make different combinations to 10.

In the following pictures, students were invited to play a game of Dot Card Memory.  They had to match different arrangements of dots that represented the same number.

Students were matching the numeral to the corresponding number of dots.

In this activity "Snowman Makes 10", students rolled a dice and put the corresponding number of cotton balls on the paper.  We recorded the different ways we made 10, and looked for similarities and differences.  Students could be heard saying "I need a 6 because I already have 4" and similar utterances.

We have been exploring a number line.  In this activity, the students were given a numeral and asked to find it's spot on the number line.  Some students were going directly to where their number was located, showing a knowledge of where numbers fall on a number line.

In the activity "In and Out", students emptied a cup of 10 cubes onto a paper that contained a circle labelled "in".  They counted and wrote down how many cubes landed inside the circle and then how many landed "outside" of the circle.  Students constructed addition statements such as "5+5=10".
