Early Numeracy and Arithmetic - Math Material



"The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree."
Aristotle


Outline first five activities and explain the reason for the sequence in which they are presented.

1 - Large Number Rods (fixed quantity)
2 - Sandpaper Numerals (fixed symbols)
3 - Large Number Rods and Cards (fixed quantity and loose symbols)
4 - Spindle Box (fixed symbols and loose quantity)
5 - Cards and Counters (loose quantity and loose symbols)
are the five activities in the sequence of their presentations.

The sequence of these introductory activities for numbers 1 to 10 starts with, 
1- oral counting of numerals 1 to 10 and visualizing the length on large number rods, 
2- recognizing the numerals 1 to 10 on sandpaper numerals
3- corresponding loose symbols to fixed quantity on large number rods and cards
4- corresponding loose quantity to fixed symbols on spindle box
5- corresponding loose quantity to loose symbols on cards and counters

Large number rods activity is an introduction of numbers 1 to 10 in form of fixed quantities.  It helps in visualizing the variation in length and colour coded segments of equal length.  The child develops a sense of order of numbers from shortest to largest or from largest to shortest.  While counting the segments orally, he/she understands that one is the smallest number, 2 is greater than 1 and 10 is the largest number.  The control of error is there to put rods in sequence to build a stair.  

Sandpaper numerals are the introduction of oral numbers 1 to 10 in their particular formation.  Through large number rods, the child has already developed the sense that the numerals will begin with 1 as first and the smallest number and ten will come in the last.  Through this activity, the child learns the recognition of numerals and is prepared for writing by tracing them with the index and middle finger.

After the first two activities, the child is able to recognize the numerals and understands their sequence from smaller to greater.  

The third activity, Larges number rods and cards, reinforces the concepts of numerals by their correspondence to the correct number rod, randomly and then in sequence.  In large number rods with cards, the child places the cards (symbol) to the rods (fixed quantity).

Spindle box consists of a wooden box with numerals 0 to 9 written on the back (fixed symbols) and 45 spindles (loose quantity).  The child compares the loose quantity which is spindle with fixed symbols which is numerals.  In addition to pairing numerals with spindles, it introduces the concept of zero for nothing or empty.

Cards and Counters in sequence to learning numerals, reinforces the child’s ability to recognize, count and compare the loose quantities with loose numerals.  This activity can be an introduction to the concepts of ‘more and less’ and ‘even and odd’.

Outline the sequence of exercises and pre-requisite in golden bead material.

1 - Teaching the names of the quantities
      Golden beads for one unit, one ten, one hundred and one thousand
      Three-period lesson

2 - counting through quantities
      Golden beads for 9 units, 9 tens, 9 hundreds and 1 thousand
      Starting from units, counting down to 9 and adding one more to start the column of 10.
      Starting with tens, counting down to 9 tens (90) and adding one more ten to start the 
      coloumn of 100.
      Starting with hundreds, counting down to 9 hundreds and adding one more hundred to start 
      the column of 1000.

3 - Bead practice
      The bank of golden beads

4 - Naming the symbols - Large Number Cards 
      A set of cards showing 1 unit, 1 ten, 1 hundred and 1 thousand
      Three period lesson
      
5 - Counting through with symbols
      Set of Large Number Cards - all quantities 1 to 9 - new column starts at 10

6 - Practice with the symbols
      Set of Large Number Cards - overlapping cards to make large figures
      Reinforcement of Ex # 4 and 5

7 - Combining quantity (beads) with symbols (LNC)
      Set of Large Number Cards and quantity of Golden Beads (the bank)
      Collect beads and then corresponding LNC
      Reinforcement of Ex # 3 and 6

8 - Combining quantity and symbols in sequence - Bird's Eye View
      Golden Beads - all quantities in 45 pieces and set of LNC
      Stacking up number cards in hierarchical order and then the corresponding beads
      Reinforcement of Ex # 2 and 5

9 - Changing unlimited quantities and carrying over
      A bead bank, set of Large Number Cards
      Introducing the idea of carrying over when beads are add up to 10 or higher number.

Pre-requisite for golden bead material, 
- The child can count and can recognize numbers 1 to 10.
- He/she has the ability of corresponding between symbols and quantities.

4 - Addition Strip Board
     Strip board, 2 sets of number cards, stage 3 card, pen/pencil
     Counting up to 18

Early Subtraction Activities 
1 - Subtraction with Short Bead Stair
      Short bead stair, marker, exercise cards
      recording subtraction
