EXPLAIN HOW AND WHAT YOU WILL USE TO TEACH THE DOUBLE AND NEAR DOUBLE
CONCEPT TO LEARNERS IN THE FOUNDATION PHASE. YOU MAY ILLUSTRATE THE
ANSWER BY USING DIFFERENT MEDIA (10) pg. 101
Different media I would use to teach the double concept are:
● Picture cards with the basic fact on the card such as a spider with 8 legs (4 + 4 = 8), two
hands (5 + 5 = 10), 2 rows of 6 eggs in a carton (6 + 6 = 12)
● Double dominoes -show learners dominoes with doubles. The learners can add the sides
together to get double answer.
● · Word problems such as Johnny and Jack each had 7 toys. How many did they have
altogether? (7 + 7 = 14). Mary had 5 strawberries and Sam had 5 oranges? How many
fruits did they have together (5 + 5 = 10).
● · Can use body parts such as hands, feet, arms and legs of which there are two. 2 hands
with 5 fingers = 10 fingers, 1 arm + 1 arm = 2 arms, 2 feet with 5 toes on each = 10 toes.
● Double chart - learners can work out using grid that double 2 is 4, double 3 is 6, double 4
is 8, double 5 is 10, double 6 is 12 …. double 9 is 18. (x-axis 0 – 9 and y-axis 0-9)
● · Flash cards – e.g double 6 – learner will call out answer which is 12.
● Doubles jigsaw (1 + 1 on one side, picture of number 2 on other side)
● Double the spots on ladybird worksheets – draw double the dots of opposite side of the
ladybird and add the sides to get the double answer.
● I would teach near-doubles once the learners understood the doubles concept. I would
explain the concept as doubling the smaller number and adding 1. Different media I would

use board to write examples. 2+3 = _, 4+5 =... I would explain this as double 2 = 4, 4 + 1 =
5 therefore 2 + 3 = 5, double 4 = 8, 8 + 1 = 9 therefore 4 + 5 = 9.
● Use a dice. Roll the dice. If roll a 5 then learner must say “5 + 6 = 11”.
DOUBLE OR NEAR DOUBLE RELATIONSHIPS
- Understand that the double of 2 is 4/ 4 is equal to double 2 – this knowledge can be attained
when learners can count well (backwards forwards skip count)
- Understand 2 and 2 = 4/ for 7 they understand to be double 3 and another 1.
- Maths games can be used – roll dice and double the number.

NAME 2 GROUPABLE AND TWO PRE-GROUPED MODELS FOR TEACHING PLACE VALUE.
pg. 127
2 groupable models:
· Counters & cups (10 single counters in a cup)
· Interlocking cubes (10 single cubes form a bar of 10)
2 pre-grouped models:
· Bean sticks (beans glued to craft sticks) – 10 sticks = 100
· Strips and squares made by teacher from mount/poster board.

*NAME AND DISCUSS 5 DIFFERENT MODELS THAT ONE CAN USE TO TEACH PLACE-
VALUE (10)
MODELS FOR PLACE VALUE:
1. GROUPABLE MODELS:
• Models that most clearly reflect the relationships of ones, tens, and hundreds are those
for which the ten can actually be made or grouped from the singles.
• Counters and cups:
• o Ten single counters are placed in a cup.
• o Hundreds: Ten cups in a margarine tub.
• Interlocking cubes:
• o Ten single cubes form a bar of 10.
• o Hundreds: not very convenient.
• Bundles of sticks :
• o If bundles are left intact, these are pregrouped model.
