# Quick Math Jr.

Build Number Sense: Practice counting, skip counting, subitizing, ordering numbers, mental arithmetic, formal addition and subtraction, and more.

Adaptive Difficulty: Quick Math Jr. learns from your progress and adapts as you play, giving questions at the appropriate challenge level. Progress from multiple-choice to writing answers directly on screen.

Create Your Own Monsters: Get creative with the monster maker and watch as your own characters appear in the game!

Quick Math Jr. is a mathematics learning app designed to give children the experiences with number they need to develop a strong number sense.

Children have a strong number sense when they understand what number means. Number sense development in the early years has a big impact on future mathematics achievement, so it’s important for young children to have a lot of practice.

Children develop number sense over time, through different experiences with number. There are many different concepts that go into building a strong number sense, including understanding of:

• What numbers mean;
• The way numbers relate to each other;
• The relationship between number and quantity;
• And informal number operations, such as adding to numbers or taking numbers away.

Quick Math Jr. helps children develop their number sense with fun games that adapt to your child’s current level of knowledge.

Quick Math Jr. is aligned with preschool and kindergarten curriculums, and helps children progress from beginner counting games to formal addition and subtraction. Quick Math Jr. even recognises your child’s handwriting, so children also practice handwriting skills as they progress from tracing numbers to handwriting their answers on screen.

## Quick Math Jr. Games

### Number Match Monsters

Count the monsters and make matches between different representations of number including dot patterns, numerals and number words. This game builds counting skills and number knowledge. As players progress, they are introduced to formal addition and move from multi-choice to handwritten responses.

### Spotlight on Subitizing

Quick! How many monsters did you see? Subitizing is the ability to quickly and accurately determine quantity without counting, and is important for the development of formal arithmetic. Players move from perceptual subitizing to conceptual subitizing, a more difficult task requiring mental arithmetic, visualisation, pattern-recognition skills, and understanding of part-whole relationships.

### Number Memory Mansion

How many monsters are inside? Players will need to keep track as monsters arrive and leave. This game encourages counting on, counting back, and skip counting, and also builds working memory, attention and visualisation skills. As players progress they will need to keep track of more changes and deal with addition and subtraction of groups.

The monsters are waiting in line at the bus stop—how many go on this bus? Players match the number of monsters on the bus to the number on the traffic light by composing and decomposing numbers in a ten-frame ‘bus’. Players progress from simple counting to formal addition and subtraction problems with numbers 0–20.

### Number Line Train

All aboard! Can you put the monsters in the right seats? Players practice the number sequence to 100 by putting numbers in the right order. Play progresses to include counting from numbers other than one, counting backwards, and counting by twos, threes, fives, and tens, both forwards and backwards.

### Place Value Boat Balance

Can you balance the boat by making sure both sides have the same number? Players learn about equality and place value by matching numbers using tens and ones. Play progresses from one-to-one matching to using tens and ones to build one- and two-digit numbers.

## Further Learning Ideas

### Support your child’s learning by adding number games to everyday play. Here are some ideas to get you started!

• Out and about? There’s plenty of opportunity for number practice! Count the number of stairs you walk down or the number of ducks in the pond. What number bus are you catching or what platform does your train leave from?
• Help children to develop number sense by playing games with number, e.g. dominoes or memory with regular playing cards. Make sure to read out the number represented on cards as you play.
• If you are feeling creative, make your own playing cards with numerals, number words and dots laid out in different ways (e.g. dice patterns, circles or lines). These can be used to play memory, snap or similar card games by matching different forms of the same number.
• Create your own flash cards to play subitizing games, or play snap with regular playing cards.
• Create mailboxes and mail letters using different number representations.
• Practice the number sequence with dot-to-dot activities or boardgames such as Snakes and Ladders.
• Create and cut out your own monster buses and monster passengers! Role one to three dice to see how many monsters need to go on the bus. Once the bus is full, do the opposite by rolling the dice to see how many monsters need to get off.
• Create a paper pizza and a variety of different ingredients. Pick one ingredient and roll a die. Add that number of the ingredient to your pizza. Pick a different ingredient and roll the die again. Add that number of the second ingredient to your pizza. Count up all the ingredients on your pizza. What is the total? Older children can write number sentences. This can also be done with plain counters if you prefer!
• Using play money and a non-transparent money box, roll a die and put that number of coins in the box. Roll the die a second time and add more money to the box. Without peeking, work out how many coins are in the box now. Older children can progress to taking coins away and working out how many are left.

Foundation Year

#### Number and Algebra — Whole Numbers

• Establish understanding of the language and processes of counting by naming numbers in sequences, initially to and from 20, moving from any starting point (ACMNA001)
• Connect number names, numerals and quantities, including zero, initially up to 10 and then beyond (ACMNA002)
• Subitise small collections of objects (ACMNA003)

#### Number and Algebra — Addition and Subtraction

• Represent practical situations to model addition and sharing (ACMNA004)

Kindergarten

#### Counting and Cardinality

##### Count to tell the number of objects.
• CCSS.MATH.CONTENT.K.CC.B.4

Understand the relationship between numbers and quantities; connect counting to cardinality.

• CCSS.MATH.CONTENT.K.CC.B.4.A

When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.

• CCSS.MATH.CONTENT.K.CC.B.4.B

Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.

• CCSS.MATH.CONTENT.K.CC.B.4.C

Understand that each successive number name refers to a quantity that is one larger.

• CCSS.MATH.CONTENT.K.CC.B.5

Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects.

#### Operations and Algebraic thinking

##### Understand addition, and understand subtraction.
• CCSS.MATH.CONTENT.K.OA.A.1

Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

• CCSS.MATH.CONTENT.K.OA.A.2

Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

• CCSS.MATH.CONTENT.K.OA.A.5

Fluently add and subtract within 5.

#### Numbers and Operations in Base Ten

##### Work with numbers 11–19 to gain foundations for place value.
• CCSS.MATH.CONTENT.K.NBT.A.1

Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
