A curious character called Carl has been visiting Class 2's Main Lesson and bringing along his famous counting contraption! He has been teaching the children more complex calculation and place value using hundreds, tens and single units. What a contraption! He has bags of different colours that cget filled and moved from box to box to demonstrate adding and subtracting numbers and the various units. Curious Carl has brought lots of fun to the processes and the children and Rodney have enjoyed using his counting contraption during maths lessons - what a fun way to learn maths!
