Aims and objectives
This activity supports the understanding and development of number
and place value in both integers and decimals up to 3 places.
Previous knowledge
Students should have some familiarity with the number system beyond
10 although as the resource can be tailored to suit individual or
group needs then the activity can be set as easy or as hard as is
required.
In the classroom
Start by selecting the type and range of numbers you want students
to be tested on. This can be integers (whole numbers) or numbers
with decimal places. Once you have chosen the type of number, select
the range that you want the students to work with then click the
'Start' button.
Students are given a random target number that you have make up
by clicking on the number columns. These columns represent units,
tens, hundreds, thousands etc. depending on your original choice.
You may find it useful to have a record of student performance for
this exercise. The Print button will give you a print of the screen
which also shows the number of correct answers for that activity.
This not only provides a record of achievement but is also a useful
diagnostic tool.
Using the worksheet on an OHP and, with a dry marker, circling
numbers from the columns is an effective way of encouraging students
to read out the numbers so that they can practice their vocabulary.

Resources type: |
The place_value_charts.pdf contains a pair of
place value charts which cover the numbers from 0.001 to 999,999.999.
These can be printed out onto acetate and used with a dry marker
on an OHP for whole class work or printed onto stiff paper and
laminated as a reusable wipe-clean resource. |
