## Hands-on maths; multiplying, clocks & time, sequencing and skip counting.

Here are the last couple of tray activities for our hands-on maths this term. While I have changed the way we are using the trays (Yes – again!) it has worked well to have the concepts we are covering in our Math-u-see books available for hands-on practise using concrete materials. As the children work through their books they are able to stop and spend extra time on a new skill using the trays if it is not immediately grasped from the instruction DVD that goes with the written material.

Curtain rings and flat wooden beads work well to illustrate the concept of “lots of” or “groups of” as the children learn basic multiplication skills.

These clock and time cards printed out from the internet start with a set of just the hours, then minutes, then half hours and finally a mixture of all 3. I googled clock/time worksheets and printed them before cutting them up. There are lots of options available online.

Learning to sequence numerals is made easy with the use of a number strip to follow. Initially the children use only the numerals 1 to 5 then up to 10, then 30 and so on. Eventually the number strip is removed as well.

Skip-counting and money concepts can be learnt by marking each interval with paper triangles and laying out real coins. I happen to have a bunch of one and two cent coins stashed away so we use those as well, although I do make sure the children know they are no longer legal currency.

## Hands-on maths; rounding numbers

Free printable number strips below.

While I have a moment I thought I’d continue to post about our maths activities with free printables for each activity.

Using a number line to teach children the concept of rounding to the nearest 10, 100 or 1000 helps to make the concept a little clearer. I printed out these number strips and used a hole punch to make holes above each number. The children select a number card, poke a golf tee into the hole closest to that number and then count the holes or hops it takes to reach the nearest 10/100/1000 in each direction. The smaller the number of hops, the closer the number and therefore they know which way to round; up or down.

This skill requires a firm grasp of number order and an understanding of place value in order for a child to be successful. The printable strips start with a blank space so that they overlap slightly and can be laid out in one long number line 0 to 100, 100 to 1000 and 1000 to 10000.

## Hands-on maths; ordinal number

(Free printable ordinal number cards below)

For a child who has a strong grasp of numbers and number order, ordinal number is a simple concept. Applying the labels of first, second, third etc. is something that children are exposed to in their everyday life. Every child is familiar with the phrase “Me first!”

This activity tray takes the concept of ordinal number and gives children practise in using it to label the order of runners in a race, months of the year and days of the week.

## Hands-on maths; subtraction activity trays

(Free printable subtraction cards below)

Today I am continuing with my hands-on maths series (addition here, solving for the unknown here) with subtraction activities for hands-on learning. This (above) is what the “activity centre” looks like on my shelves. I would love to have it all spread out on individual trays but there is just not enough room. A simple plastic box and re-purposed desk organiser do the job and the children take out the materials they wish to use for the day.

You can use any materials you like but it is helpful if there is some way to clearly show that they have been subtracted or taken away. I have out wooden craft pictures that are turned over as they are subtracted, miniature fruit erasers that stand up and are then laid down as they are taken away, double sided 2-colour counters, Duplo blocks and some random plastic connecting pieces that clearly have 2 different sides. You can have the children physically move the pieces or put them in a separate container or some other method of showing that they are subtracted but I think it is good to be able to still see how many have been taken away as it helps with self-correction of errors.

The children choose one set of subtraction cards at a time to work on, beginning with the easier subtract 1 or 2 cards and then moving on to the more difficult combinations once they are able to do these without needing manipulatives. The aim is to have these basic maths facts committed to memory or so quickly worked out mentally that higher level mathematical skills based on them are not slowed down by having to work out the simpler steps. For your copy of my free printable subtraction cards click here: vertical-subtraction.)

## Addition tray activities for hands-on maths

After my earlier post on addition tray activities I have had some requests for a copy of the addition cards so here are your free printable vertical addition problems ready to print and laminate.

## Hands-on maths; solving for the unknown tray activities

(Free printables below!)

Success in higher level maths requires mastery of basic addition, subtraction, multiplication and division concepts. The answers need to come quickly, without requiring mental effort to work them out, otherwise the more difficult problem solving is slowed considerably and errors result. Working through simple problems over and over cements the answers in children’s heads and helps them stay in long-term memory. Lets face it though, page after page of the same kind of problems in a maths textbook can be… well.. boring!

My solution is to gather a range of attractive materials and allow the children to complete problems repeatedly, but in a way that means they hardly notice it is the same skill over and over.

These are our ‘solving for the unknown’ trays and like the addition trays, the cards are in sets. This cards all have the same end total, for example 0+_=3, 1+_=3, 2+_=3 and 3+_=3. Containers of the same number as the answers are filled with 2 distinctly different types of materials to illustrate the problem shown on the cards. The children can start with the smaller numbers and work on them until they no longer need manipulatives and can compute them almost instantly before moving on to the larger numbers.

The materials are attractive and any cards they can already do they simply tell me the answer to and set aside so that they are not wasting time practising combinations they already know.

Not all learners love hands-on activities. My 7 year old book work lover is happily working through page after page of these same problems in her maths text. She finds manipulatives frustrating and thinks that they slow her down. When she meets a problem that she cannot do in her head or on paper, she pulls out the relevant materials and works it through until she can move on – in her book. Children have different learning styles and maths is one subject that can easily be adapted to suit.
