100 Chart

It is very important to your child’s number sense development that he or she  learns to recognize patterns found on the 100 chart.  Recognizing patterns is an essential step to understanding the number system so that he or she can be successful at addition and subtraction activities. Many kids skip this stage of learning and go right to memorizing facts (2 +2=4) and this can really hinder learning for later on! Here to two games your child can play that promote this!

Base Ten Blocks – Math

Base ten blocks are a new manipulative that has been introduced in Grade One. Children in Kindergarten are very familiar with five and ten frames but the base ten blocks are brand new. During September and October children have been exploring the base ten blocks during Guided Exploration by building with them, sorting them and by counting the sections. During the month of November we have been using the Base Ten Blocks to represent the date on the calendar. Children in grade one need to learn to represent numbers to 50 using a variety of math tools (10 Frames, Base Ten Blocks, Number Lines, Coins).

Counting on is an essential skill when using base ten blocks and practising this concept is helpful. For instance you could put one of the rods (base ten block worth 10) down and then 7 of the ones and your child would say 10 then count on to 17 by counting the ones. Counting on is essentially saying the biggest number and then counting on the rest to see how many you have altogether. Children need to develop this strategy on their own and, with lots of practice counting on in different situations, they will.

Math Activities Using 5 & 10 as an Anchor

Below you will find many interactive games to help your child develop the strategy of using 5 and 10 as an anchor in math.  This skill along with seeing patterns in numbers on a 100 chart is the foundation of what higher level math skills are built on.  Children need lots of practice using and explaining or talking about how they got their answers.

Help BT Bear Catch 10 Blocks


This year in grade one we explore the concept of patterning in many different ways that are meaningful to the children. The children have many opportunities to identify, describe, extend and create repeating patterns.

A pattern is something that is arranged following a rule or rules.In grade one children are expected to create and extend their own patterns using at least one attribute (e.g. colour, shape, size, thickness) by the end of the school year. Patterns often occur naturally in play using materials in the classroom. Children in grade one often use patterns without even thinking about what they are doing. Patterns appear while building with blocks and other building materials, while creating designs with loose parts and math manipulatives or during work with the creative centre materials. I will be supporting your child’s growth in vocabulary related to patterning by pointing out the patterns I see in their work and introducing new terminology that will be the foundation for their future learning.

Patterns appear everywhere in our natural world as well.  The seasons occur in a pattern, the days of the week and the months of the year are a pattern as are many songs and some of the stories that we read at school.  Your child’s ability to recognize and talk about patterns in the natural world (e.g. on flowers), on clothing (e.g. a design on a shirt) or around your home (e.g. floor tiles) will increase throughout the grade one year as she or he becomes more familiar with patterning vocabulary.

Patterns are the foundation of our number system as well.  It is important that children learn to look for patterns in numbers in order to have a good understanding of number sense.

During our morning calendar discussions we regularly look for, talk about and describe the patterns we see on our 100 chart in the classroom and on the calendar. We have many opportunities for patterning when we count by 1’s, 2’s, 5’s and 10’s to 100, both forward and backward.

Making connections to what we are learning in patterning at school is easy to do at home. Try these activities with your child:

-use small materials you have at home to create patterns (e.g. Lego, cutlery, blocks)

-use a calendar and explain what events in your lives occur in a pattern (e.g. work/school days are Monday through Friday but every Saturday and Sunday is a day off;  swimming lessons are on Tuesdays and Thursdays each week) Be sure to talk about what stops the events from being a pattern (e.g. PD Days/Sick Days/Holidays).

-use a 100 chart on the internet to look for patterns as your child counts

-look for patterns in your home on furniture, on walls and flooring and on clothing


Patterning Vocabulary:
core: the smallest part of the pattern that repeats
extend: identify the pattern (the core) and keep repeating it
attribute: characteristic that describes how the object is changing

10 Frames

At school have been using a 10 Frame as a tool for representing numbers. Please take some time to watch the first video as it explains the concept of a 10 Frame for parents. The last 2 videos are games to play. As your child gets better at understanding numbers represented on the 10 Frame he or she will be able to get more of the answers correct in the game videos without having to count each section of the 10 Frame.
