The students draw five articles of clothing anywhere on their grid by copying the shaded clothes examples on their worksheet. Then the students are divided into pairs. The object of the game is to call out coordinates (e.g. b - 4, g - 9) to try and find the clothes on their partner's grid. If a student gets a ‘hit’, they shade the square. If the square is blank, the student says "Miss." When a student finds an article of clothing, they can ask: Is it a (shoe)? or Are they (shorts)? However, a student can only ask the question twice for each item of clothing they find. Their partner replies appropriately. The first student to find and shade in all their partner's clothes wins the game.
Dadas dos magnitudes, se conocen la equivalencia entre un valor de una y el valor de la otra. Entonces para cada nuevo valor que se de a una magnitud calculamos el valor proporcional inverso de la segunda magnitud.
Decimales periódicos Una fracción es un cociente entre dos números enteros. La división de esos dos números da lugar a una expresión decimal con un grupo de cifras que se repiten periódicamente, el llamado periodo, y que puede ser:
Fracción generatriz Todo decimal periódico puede expresarse en forma de fracción a la que llamaremos fracción generatriz. Decimal exacto Se divide el número sin coma, por la unidad seguida de tantos ceros como cifras decimales hay. Decimal periódico puro En el numerador se escribe la diferencia entre la parte entera seguida del periodo y la parte entera, en el denominador tantos nueves como cifras tiene el periodo. Decimal periódico mixto En el numerador se escribe la parte entera seguida de las cifras hasta acabar el primer periodo menos la parte entera seguida de las cifras hasta comenzar el periodo, en el denominador tantos nueves como cifras tiene el periodo seguidos de tantos ceros como cifras hay entre la coma y el comienzo del periodo.
Technically, there are only two tenses in English.
Present Simple and Past Simple are considered “true” tenses because the verb changes its form to make them (are inflected), not by adding an auxiliary.
Present simple: the verb changes in the third person singular form by adding an ‘s’ to the base form e.g. I swim. He swims. They eat. She eats.
Key words: always, usually, often, sometimes, seldom, rarely, never, every day, on Sundays, etc.
also stative (non-progressive) verbs: know, understand, believe, feel, think... But when it has a future meaning (scheduled events): on Monday, next week, ...
Past simple: regular verbs change by the addition of -ed to the base form and irregular verbs change their form completely. (e.g. I walk to work. I walked to work. I eat sandwiches. I ate a sandwich.) There are a few verbs that don’t change (such as ‘put’), but these are rare cases.
Key words: yesterday, last week, last month, ago, in 1979, this morning (when meaning is past), etc
There are two aspects: the perfect aspect and the continuous aspect.
The continuous aspect shows that the speaker considers the action to be temporary and it is either of some duration or it is repeated. And this is why some verbs are rarely used in continuous form (think, believe, love, etc) - because the speaker can’t control whether they are temporary or not.
Key words: now, right now, at the moment, Look!, Listen!, etc. But when it has a future meaning (fixed plan): tomorrow, today,...
Key words: while, when
The perfect aspect conveys the concept of ‘looking back’.The exact time, especially of the earlier event, is often not known but the relationship between the times is important and gives a sequence of events.
Key words: already, yet, just, ever, never, ___ times, since + a particular time, for + a duration of time
Hoy hemos hecho sudokus de animales (Ver vídeo).
Primero hemos identificado los animales del juego y con la tijera los hemos recortado. Y luego, con paciencia hemos razonado qué animal faltaba en cada celda (sólo puede haber un animal de cada tipo en cada fila y columna).
A "sequence" (or "progression", in British English) is an ordered list of numbers; the numbers in this ordered list are called "elements" or "terms".
Arithmetic sequences are used in daily life for different purposes, such as determining the number of audience members an auditorium can hold, calculating projected earnings from working for a company and building wood piles with stacks of logs. There are many uses of geometric sequences in everyday life, but one of the most common is in calculating interest earned.Physicists use geometric progressions to calculate the amount of radioactive material left after any given number of half-lives of the material. During each half-life, the material decays by 50 percent.
So, imagine that during this Xmas holidays, you are given presents for 12 days.
