MATHEMATICS 5 CURRICULUM GUIDE 2015
Specific Outcomes
NUMERATION
Suggestions for Teaching and Learning
Students will be expected to:
Number
5N8 Continued...
5N8.5 Express a given hundredth 
as an equivalent thousandth.
5N8.4 Express a given tenth as 
an equivalent hundredth and 
thousandth. 
In Grade 4, students used money (dimes and pennies) to explore the 
equivalence of tenths and hundredths. For example, 20 pennies (0.20) 
was equivalent to 2 dimes (0.2). In Grade 5, equivalence will include 
tenths, hundredths and thousandths and therefore thousandths grid 
paper (or decimal squares) will be needed.
Distribute tenths, hundredths and thousandths grids. Ask students to 
shade three columns on the tenths grid, 30 squares on the hundredths 
grid and 300 rectangles on the thousandths grid. Use coloured leads 
or markers in order to outline the subgroups reflected by each decimal 
number. This helps students see that these decimals are equivalent.
Achievement Indicators:
Beat the Teacher Game
Students and teacher each have a piece of paper. The teacher informs 
the students of the place values of a mystery number up to one million 
with as many as three decimal places. (Note that students are not 
responsible for numbers greater than one million.) Students and teacher 
create the skeleton of the number with segments as shown:
___ ___ ___ ___ ___ ___ . ___ ___ ___
The teacher rolls a number cube and each player decides in which place 
he or she will place that digit (in the ones, tens, hundreds ... place). 
Unseen, the teacher and students record the digit. Continue until all 
places are filled. When all blanks are filled, the teacher shows his or her 
number and the students each determine whether they have beaten the 
teacher (i.e., created a number which is greater than the teacher’s).
This process may start early in the unit with whole numbers and expand 
to include decimal places.
5N8.6 Represent an equivalent 
tenth, hundredth or thousandth 
for a given decimal, using a grid.
