Recommended for Prep-Grade 2
Dot arrays in a tens-frame encourage children to subitise - to
see a visual pattern for the numbers 1-10 and automatically
recall them. These dot frame pieces allow children to manipulate
the parts of the tens-frame to discover the tens facts and the
part-part-whole relationships of the numbers from 1 to 10. Also
a great manipulative for exploring doubles facts and fractions.

Teaching Suggestions :
Level One
Use the puzzle pieces to develop students' knowledge of numbers
to 10 by:
- giving students one piece
and asking them to count the dots and write the numeral in
the matching colour
- using the complete set of
puzzle pieces ask students to order the pieces from the
smallest number to the largest number of dots
Use the puzzle pieces to
explore the part-part-whole relationships:
- for example number 4; 2
dots and 2 dots are the same size as the 4-dot piece and 1
dot and 3 dots are the same as the 4-dot piece
Use the puzzle pieces to
explore simple addition facts to 10:
- students can choose any 2
puzzle pieces and practice the "count on" strategy to find
the total of the 2 pieces
Use the puzzle pieces to
explore simple subtraction facts about 10:
- students can cover the
full tens-frame piece (10 pink dots) with another piece and
count the number of pink dots showing to get the answer
Level Two
- As a whole class give
students a piece of puzzle and ask them to find their
partner to form a tens fact. Write them on the board. Look
for the patterns.
- Using the full tens-frame
(10 pink dots) as a baseboard, cover part of it with one of
the puzzle pieces. Students can then see the part that
remains of the full tens-frame and write the tens fact.
- Students match the pieces
together on a blank tens-frame to form all the tens facts.
- Working in pairs or a
small group, turn all the puzzle pieces face down. Students
choose two shapes and turn them over to get a tens fact. Keep
the pieces if they match. Winner is the person with the most
pieces. (You may choose to use more than one set for this
activity depending on the size of the group.)
- Use a 0-9 ten-sided dice
with the puzzle pieces. Roll the dice and choose the puzzle
piece that combines with the number to make a tens fact.
- Extend student's
knowledge to number facts to 20 by using the full tens-frame
(10 pink dots) and then 2 other puzzle pieces. E.g.: use the
10 and 3 piece to make 13: students can then explore what
other piece they need to add to make 20.
- Use the puzzle pieces to
investigate doubles facts to 20.
