I have decided to start providing some internal PD for staff at our fortnightly staff meetings. We have a number of staff who have the NZ Dip in ECE but minimal formal Montessori training. I will start at the beginning with: (see wikieducator link below)
Indirect Preparation for numeracy which is an awareness of cardinal numbers, ordinal numbers, numerals, one to one correspondence, sequencing and tally counting. Also concepts of size, length, area and volume. These activities are for infants and toddlers.
The Pink Tower: This is part of the sensorial education but is also a preliminary maths activity. It develops visual discrimination of size and volume.
The Broad Stair: Visual discrimination of thickness and differences of two dimensions – area
The Long Red Rods: Visual and muscular discrimination of length.
Direct preparation: Learning Numbers 0 – 10
1.number rods – This activity is the child’s first experience with a fixed quantity.
The purpose of this material is to learn the quantity of numbers 1 – 10, to learn the names of numbers 1 – 10, to associate the names with the quatities (tally counting), to learn that there is a relationship between numbers 1 – 10, to show that each number is a composite of other numbers. Also it is indirect preparation for the decimal system.
