# Mathseeds Content Overview

## Kindergarten

### Lessons 1 - 50

The first 20 lessons are for children with little or no mathematical skills. Children learn fundamental number skills including number recognition, number words and counting. The Mathseeds characters led by Mango introduce a range of skills including recognizing the shape of each number 0-10 and one-to-one correspondence. Children are also introduced to the four basic 2D shapes: circle, square, triangle and rectangle, colors and some simple concepts of size: big, small, short, tall etc.

Lessons 21 - 50 develop growing mathematical skills. Children learn to count forwards and backwards to twenty with confidence. They use a range of techniques including ten frames and number lines. They also learn the number words up to twenty. Addition is introduced and children add up to ten and doubles to five. Mango and the other Mathseeds characters present the concepts of passing time, life cycles and days of the week during these lessons. Children develop their understanding of 2D shapes by sorting them according to their properties. They are also introduced to four 3D shapes: sphere, cube, cone and cylinder.

Kindergarten Lessons Overview

### Lessons 51 - 100

Mathseeds Lessons 51 - 100 build on the skills children have acquired earlier in the program. Children learn to count to 100, order numbers and identify ordinal numbers to 10th. An understanding of place value is developed, including trading ones for tens. Children identify US money and investigate fractions, focusing on wholes, halves and fourths. Subtraction is introduced, and children initially add and subtract to 10, and then to within 100. They also learn how to solve subtraction problems with an unknown addend. Strategies include counting on, counting back, near doubles and using number fact families. Children learn how to skip count by 2s, 5s and 10s, as well as early multiplication and division skills of grouping and sharing. The concepts of area and volume are introduced in these lessons, and children continue to investigate the attributes of 2D shapes and 3D objects. Children follow simple directions to a particular location and learn to read digital and analog clocks to the half-hour. Tally charts and simple picture graphs are introduced. Children also work with the concept of chance and the likelihood of things happening.

### Lessons 101 - 150

Mathseeds lessons 101 - 150 introduce a range of new concepts and consolidate skills taught previously. Children learn to count to 1000, identify odd and even numbers and round to the nearest 10 and 100. They continue to develop place value skills; composing and decomposing numbers to 999. Addition and subtraction strategies are further developed, including the ‘jump’ and ‘split’ methods, as well as vertical addition and subtraction. Children continue to practise grouping and sharing and use of the multiplication and division signs. They are also taught how to find fractions of a collection of items. Children investigate length and are shown how to measure in metres and centimetres. They investigate the way 2D shapes move and reflect, as well as how 3D objects are constructed. Children tell the time to the quarter-hour and the nearest 5 minutes, and use a calendar to identify particular dates. They construct tally charts and simple picture graphs, and interpret data in a variety of ways.
