*"An intuitive ***sense** of **number** begins at a very early age. ...Piaget called this ability to instantaneously recognize the **number** of objects in a small group 'subitising'. As mental powers **develop**, usually by about the age of four, groups of four can be recognized without counting." from **https://nrich.maths.org/2477**

Our main focus in Kindergarten math is developing **number sense.** We use Envisions, Math Investigations and Kathy Richardson’s ,Developing Number Concepts.

Students learn to explain their thinking as they work through hands-on activities.

Students develop strategies for accurately counting quantities to 10 and beyond.

Students have repeated experiences joining (adding) two or more amounts, removing (subtracting) an amount from a whole, and decomposing a number into two or more parts (place value).

Throughout the year we will discuss counting, decomposing numbers up to 10, measuring lengths, patterns, functions, geometry (2-D and 3-D shapes), addition and subtraction, as well as data analysis.

Following the Common Core State Standards, we will explain our thinking verbally as well as in writing.
