I choose this chrome extension because it easy for the teacher to access, it also got understandable instructions on how it should be played.the game teaches learners how to count numbers. it start counting from 1-10 which is easy for the grade R to count and is what the grade R are still learning.this chrome extensions does not only teach the learners how to count but it also teach them how to write the numbers , it gives them a chance to express their writing and it shows them the number after writing it and  it easy for grade R's to write because it got big and bold numbers to write in .it also help the learners to recognize numbers from 1-10  because when you write something down it easy for you to remember it back than when you just look at it.the grade  R  are expected to know how to count and how to write numbers.
