Math Games for Teachers

Year 2 - Number and Algebra

Standard 2.OA.1.1 - Complete the addition sentence by filling in the missing number with sums up to 100.

Included Skills:

Number and place value
Investigate number sequences, initially those increasing and decreasing by twos, threes, fives and tens from any starting point, then moving to other sequences
- developing fluency and confidence with numbers and calculations by saying number sequences
- recognising patterns in number sequences, such as adding 10 always results in the same final digit
Recognise, model, represent and order numbers to at least 1000
- recognising there are different ways of representing numbers and identifying patterns going beyond 100
- developing fluency with writing numbers in meaningful contexts
Group, partition and rearrange collections up to 1000 in hundreds, tens and ones to facilitate more efficient counting
- using an abacus to model and represent numbers
- understanding three-digit numbers as comprised of hundreds, tens and ones/units
- demonstrating and using models such as linking blocks, sticks in bundles, place-value blocks and Aboriginal bead strings and explaining reasoning
Explore the connection between addition and subtraction
- becoming fluent with partitioning numbers to understand the connection between addition and subtraction
- using counting on to identify the missing element in an additive problem
Solve simple addition and subtraction problems using a range of efficient mental and written strategies
- becoming fluent with a range of mental strategies for addition and subtraction problems, such as commutativity for addition, building to 10, doubles, 10 facts and adding 10
- modelling and representing simple additive situations using materials such as 10 frames, 20 frames and empty number lines
Recognise and represent multiplication as repeated addition, groups and arrays
- representing array problems with available materials and explaining reasoning
- visualising a group of objects as a unit and using this to calculate the number of objects in several identical groups
Recognise and represent division as grouping into equal sets and solve simple problems using these representations
- dividing the class or a collection of objects into equal-sized groups
- identifying the difference between dividing a set of objects into three equal groups and dividing the same set of objects into groups of three
