Parent Workshop
Mathematics
Aims:
- To demonstrate how we teach
Mathematics in Reception to Year
2
- To allow time for you to play with
some of the resources we use
- Give you some ideas of
games/resources you can play with
at home
Addition
+
Reception
~ Using quantities & objects add two single-digit numbers
~ Count on back to find an answer
Year 1
~ Addition with numbers up to 20
5+3=
Using numicon
demonstrate how you
would solve the
following question;
7+4 =
Year 2
~ Addition with two digit numbers
34 + 11 =
By counting on a ten and adding a one
Using base 10
demonstrate how you
would solve the
following question;
42 +23 =
Year 2
~ Addition with two digit numbers
34 + 13 =
Add by partitioning on a blank number line….
Year 2
~ Addition with two digit numbers
using column addition
34 + 27 =
T

Multiplication
x
Reception
~ Solve problems involving doubling
~ Solve practical problems involve combining
groups of 2, 5 or 10
Numicon picture
Year 1
~ Multiply using concrete objects, pictorial
representations and arrays with the support of
the teacher
2+2+2=
Using numicon
demonstrate how you
would solve the
following question;
2 + 2 + 2 +2 =
Doubles
+
= 4
Year 2
~ Multiply using arrays and repeated addition
(2’s, 5’s & 10’s)
Repeated addition – using concrete apparatus, numicon, on a
number line & a bead bar
Commutativity - array
Using numicon
demonstrate how you
would solve the
following question;
5x3=
Division
÷
Reception
~ Solve problems including halving & sharing
~ Solve practical problems that involve sharing
groups of 2, 5, 10 into equal groups
Numicon picture
Practical object picture
Year 1
~ Grouping & sharing in small quantities
6÷2=
Equal groups
Sharing items during play & problem solving
Using objects
demonstrate how you
would solve the
following question;
8÷2=
Numicon
Repeated subtraction on number line
Year 2
~ Calculate mathematical statements for
division & write them using division (÷) and
equals (=)
Sharing equally – children will develop their own ways of jotting
Repeated subtraction – using a number line
Solve this problem on a
number line:
Share 8 sweets between 2
people.
